Video Transcript for K Source Custom Towing Mirrors - Full Replacement Mirror - KS70103-04T Review

Today we'll be reviewing part number KS70103-04T. These are the K-Source Custom Extendable Towing Mirrors. Both the driver and passenger side mirrors are included. To see if these are going to fit your particular year, make, and model, you can refer to the vehicle list at the bottom of the product page. The mirrors replace the factory side view mirrors on your vehicle. They do offer a telescoping function that makes this perfect for those perfect for those who frequently tow a trailer, make it easier to park, change lanes, and pass.

All you got to do is pull the mirrors away from your truck to extend the lines of sight by up to 3 and 3/4 of an inch. It's really going to make it easy to see around the side of your trailer. When you're done you can just push the mirrors back in. When you're not towing or when you need to park, it makes it a little bit easier. That's going to eliminate the need for custom towing mirrors or snap-on mirrors as well as-strap on mirrors that you constantly have to install and uninstall.Each mirror is going to feature an amber turn-signal light that's built into the side of each mirror.

If I turn those there, you can see those. That's these right here. We have the spotter mirrors on the bottom that help to further reduce blind spots. The main mirrors have power adjustments and the spotter mirrors are going to be manually adjustable simply by just pressing in on the corners or the side that you need to get the angle that going to best suit your application.These mirrors are actually designed to fold up against the vehicle for parking or fitting into tight spaces. The custom design is going to provide a perfect, secure fit for your vehicle.

They are going to use the factory connections for electric, turn signal, and heat functions. You can see that there. It also has the same footprint and uses the same mounting points as the factory mirrors. Again, the driver's side and passenger's side mirrors are included.We're going to go over a few dimensions so we're just going to be using 1 mirror because the dimensions are going to be the same for each one. Overall length when fully retracted is going to measure about 20 inches.

When it's fully extended, that's going to increase to 23 and 3/4 of an inch giving us that 3 and 3/4 of an inch extension. The mirror face overall width is going to give us a measurement of right around . We're going from the end of housing to the end of the housing. It's measure about 9 inches. Overall length, measuring both mirrors, is going to be about 10 inches tall. The main mirror is going to be about 7 inches in height and the lower mirror is going to be about 2 and a 1/2 inches.Please keep in mind that you cannot upgrade to a power mirror with a heated face and turn signal if your OEM mirror is not already equipped with those features.That's going to do it for today's review part number KS70103-04T. These are the K-Source Custom Extendable Towing Mirrors. .

I love these mirrors, I can now see what’s going on behind my boat while towing. I highly recommend them. Very good quality and etrailer employees were extremely helpful. 607351

Mirrors arrived quickly and packed very secure. Installed on 2015 Tundra SR5 in about 1-1/2 hours (took my time) Everything fit perfect and I feel product is high quality. I was really happy that turn signals and marker lights worked. I did not have those features on the standard mirrors. Nice addition to the Tundra for towing and look really good on the truck. Very Happy with Purchase 489926

Lower wide angle mirrors useful. Bearing holding them maybe a tad too tight causing some effort to move them. Upper main mirrors are fair. The bearing holding them should be a little tighter. Some light flutter of the main mirror at highway speeds. Overall useful on my Tundra double cab to pull a 32 ft RV. Overall fair to good value for a non-stock part. 603773

Mirrors were delivered early. I was impressed. They were carefully packaged and look great. It took about 10 minutes to install each side. Plus the turn signal works on the mirrors also. I would recommend them to anyone that wants to up grade 415463

The mirrors arrived well packaged and with no instructions. Following easily found YouTube vid, installation was easy taking around 15 minutes per mirror. The mirrors are good quality. On my 2010 Tundra the signal, heat, and adjust features all function fine though my OEM mirrors did not have the signal feature. The driver's side mirror produces a whistle when the vehicle is moving faster than around 45 mph. I hope to fix that with a piece of duct tape... without the whistle they'd get that fifth star from me. 93234

Uh, a Google search for replace tundra mirror produces two videos among the top ten search results. Both videos where helpful. The mirror replacement is straight forward. Pulling the door interior off takes a bit of force. I hadnt done it before so didnt know quite how hard to pull. Start at the bottom as in the video, lift up and outward. There are still some wires attached so have something to set it on, or someone to hold it.

Product was relatively easy to install if you search for and follow the YouTube video. Have not had a chance to hook up my travel Trailer yet but it looks like It will be no sweat seeing all around it with theses mirrors. Service delivery time was right on the money. Thank you for the prompt delivery. Julie M at e-trailer was great at getting my shipment to me as promised thanks Julie. 106631

I put these on a 2017 Toyota Tundra. I pull a 29 ft travel trailer and couldn't see with the stock mirrors. The mirrors were easy to install. Took 30 mins all together. Was able to put them on by myself. Just like the Description said. The mirrors were packaged nicely also. Plug them in and good to go. Everything works like from factory. 376042

A little disappointing actually. Because of all the great service I've gotten from etrailer over the years, I paid a higher price than some other places on the internet. The product doesn't seal up against the truck as well as the OEM mirrors did. I reinstalled them once to make sure I'd done everything correctly. The three nuts tighten before the top corner of the "triangle" snugs up to the truck. Its a cosmetic issue as the smaller inner seal is fine. Also, one of the mirrors has a small scratch across the black plastic. This isn't etrailer's fault as the items were well packed. The power features of the mirrors all seem to work fine. 652294

This was a fairly easy job, although ripping off the door panels was a little unnerving. My truck is a 2011 Tundra and had electric/heated mirrors. I was pleasantly surprised that the built in turn signal and running lights now work! Everything was plug and play! Love them! 321740

Easy install. Came with all hardware incase you drop and/or lose the existing hardware while uninstalling OEM mirrors. No shakes or rattles. Top portion is power adjustable, bottom is manual adjust for viewing angles. My truck is a Limited and has Blind Spot Alert (BSA) & Rear Cross Traffic Alert (RCTA). These 2 features are lost and throw a dash light to see dealer. The warning is annoying, it towing visibility is more important. I'll follow up with my dealer (who actually recommends these mirrors) to see if the dash lights for these 2 systems can be deactivated. 603795

Mirrors look great and install was a breeze. It took longer to get door panel off than it did to swap out mirrors. My only complaint is that the passenger side mirror has a huge increase in how close objects appear to be to the truck compared to OEM mirror, so there is an adjustment period to get use to the mirror. 511237

What a great upgrade for my 2015 Toyota Tundra SR5! Perfect fit. Only took about 15 minutes per mirror to replace them. I didn't have blinkers or clearance lights on my stock mirrors, but these mirrors plugged right in and now I do. I do confess that they are taking me some time to get used to, but I can now see where my tire hits the ground and still have full view of the side of my truck. I can't wait to use them to pull my new travel trailer. I will no longer be a nervous wreck, constantly adjusting my mirrors so that I don't run into something. The biggest problem I see is that I can no longer park in my parking lot at work without getting out of my truck to fold the mirrors in. I'm not certain, but I would guess they add about 4-5 inches width on each side of the truck. I'm ok with that, because these things are a necessity when towing a big trailer. Thanks Etrailer! 279928

Received the mirrors in less than 3 days. checked out the video on utube and on Saturday took me about 30 mins to change out both mirrors. Mirrors look great and perform outstandingly. The lights and turn signals work even though the old mirrors did not have that. The remote positioning works and I would say the defrosters will also (still in the 80's) I have included pictures. Now I can see the back of my camper and should have an easier time backing. Thanks 146365

Unfortunately these mirrors shake/vibrate making it difficult to see images. The functionality is quite poor. Overall I’m very disappointed. These mirrors are the only negative purchase I’ve had with etrailer. Other items have been excellent and I frequently use the website for helpful “how-to” videos on various topics. 694246

I was concerned about ordering these with out seeing them. Installed in about 30 minutes and fit perfect. I would recommend getting the plastic door fasteners from Toyota first. They are made to break when you loosen the door panel. Very happy I would recommend these 693056

2017 Tundra. Broke the OEM right side mirror being careless. Really needed tow mirrors anyway, so changed them both out. MUCH better for towing our camper and enclosed cargo trailer. Fit perfectly. Watched a couple of people replace these on YouTube. Easy project. They are notably bigger than the OEM shorty mirrors, but that's kind of the point. They look very similar to the OEM extendables on quite a few makes of truck so they don't look odd when not towing. Truck still fits through 10' wide garage door with no problem. Really tight on 9' garage door without folding either if their not extended but does fit (barely). Folding the left side and leaving the right in the retracted position, it fits through the 9' door just fine. Exactly what I needed. 682221

Arrived on time and as advertised. Fit is perfect. Just watch a video or two online beforehand of how to remove the original mirrors. Took me 40 minutes total (to remove both old mirrors and finish installing the two new mirrors)... and I'm old! A bonus is now I have running lights and turn signals on the mirrors (originals didn't have them). Great job by etrailer! 655360

Excellent mirrors. I gave them to my RV dealer and had them installed as part of the purchase package. Towed a large travel trailer with them. The mirrors worked great and provided good visibility. The bottom wide angle is helpful and easily adjusted. I would buy these again if needed. 601194

These are great! Easy to install and work great. The information I read prior to purchasing said that the heat feature and signal feature might not work but they do! My only issue is the lower mirror on each side is somewhat distracting. I am extremely pleased, makes backing our trailer up so much easier than when I had the stock mirrors installed. 581748

Installed these mirrors on my 2015 Sequoia SR5 4x4. Installation is fairly easy. Door panels come off easy but are more difficult to put back on, you have to be sure the plastic snaps or keepers are aligned before popping it back in place. The mirrors themselves are decent quality but do not have the fit of the factory mirrors. I noticed a gap of approx. 3/16" at the very top of the mirror mounting bracket, it should be flush to the car body. The turn signal lights on the side of the mirror do not work with my vehicle, I read many reviews from others that said their signal lights worked despite not having that feature originally. So be prepared if they don't work. Also be sure to tighten the mounting nuts on the new mirrors, mine were not tightened down. The mirrors look good and perform the function they were designed for. 552346

When i spoke with Adam about the mirrors he promised two day shipping. I received the mirrors next day. (I am only 2 hours away from there location so this may not happen for everybody) The mirrors showed up well packed and in perfect condition. Yes the blinkers work on the new mirrors and i did not have that option on the old ones. I love the fact you can call them on the phone speak to a real person, to make sure you are getting what you need. Will be telling all my friends and family about Etrailer and ordering more parts in the future. Thank you. 511074

Installed these on a 2016 Tundra SR5 to replace the factory mirrors. Installation took about 90 minutes total; I took my time; working slow and smooth...which actually makes the job go fast :-) Some tips from my work: 1) Several videos on YouTube re: door panel removal; A1Auto had the best 5 minute video on this IMHO Also several stereo speak install videos that cover door panel replacement. 2) Take the extra minute or two and remove the door lock / window control units and to disconnect the lock cables...it's very easy, and the door panel is light...that allows for complete removal of the panel and not leaving it hanging by cables and wires. 3) I used a deep socket, 1/4 drive, 10mm to remove the locking nuts on the stock mirrors; when the nut was ~ 2 turns from being removed, I switched to a 3/8 drive, 10mm with a magnet extension to finish removing the nut...you really do not want any of the nuts dropping into the inside of your door. Really nice to have larger mirrors on the truck for towing; took it out for a drive; no vibrations; and lots of visibility on both side of the vehicle. 508827

The Tundra towing mirrors were installed in about 1/2 Hr. each. There were no problems, all the electrical functions worked extremely well. I am well pleased with the results. Anyone towing a travel trailer will be much safer using these mirrors. I went out for a drive after the installation, and at 70 MPH there was not problems. After extending to their fullest length for towing there was a little vibration in the mirror, but not enough to be a problem. But, i do not tow at 70 MPH anyway, at slower speeds there is not problem, even extended. 488280

So far so good; had my son put them on for me and he a Toyota Tech. First one took a half hour drop a nt in the door could not find it; then discovered the new one had nuts on them; second one done in 20 minutes. All this was done at nite with a flash lite. A instruction sheet would had been nice; but that's what the Kid is for. 459081

The mirrors were simple to install and work as expected. Be sure you have the trailer towing package on your Tundra so the wiring harness is correct. 451578

Mirrors came undamaged. The first mirror took me about an hour to put on and that's because I had trouble putting my door back on. There's a little metal ledge that the door sits back onto that I couldn't seem to figure out. I got the snaps lined back up, but because I didn't hook the ledge over it caused the door to bulge and it wouldn't sit right. Overall there is no vibration in the mirrors and they work great! I added a video on youtube for those who want to see. At the end of the video I include a quick freeway test ride. The mirrors DO NOT whistle as I have seen on other towing mirror reviews. The only things is they add some road noise. That's expected as they are bigger mirrors....so they catch the wind easier. It's not noticable when your radio is on. Here is the video of my install....I apologize for the bad camara angle....it was on my head and there are some parts where I'm pointing to something out of view. 451515

Mirrors fit like they should. Installation was about an 45 min. Nice having running lights and turn signals on the mirrors. I have not had towing mirrors on any truck in the past so it may be the nature of the beast, but there is a little vibration at cruising speed in the mirrors. Not enough to be concerned. Just enough to notice. I have a 2011 Tundra. Overall very happy with the mirrors. 415131

  • Recommended Towing Mirrors for 2018 Toyota Tundra
  • The K-Source Custom Extendable Towing Mirrors - Electric/Heat w Turn Signal # KS70103-04T do not have the blind spot indicator integrated. They only have the features indicated but are by far the nicer looking and more custom mirrors. If you have the blind spot feature and want to keep it, then I recommend using the K-Source Snap & Zap Custom Towing Mirrors - Snap On - Driver and Passenger Side # KS81300 but they will not stock mirrors if equipped with additional lighting features that...

  • Towing Mirror Recommendation for a 2010 Toyota Tundra SR5
  • The K-Source Towing Mirrors part # KS70103-04T are confirmed to work on your 2010 Toyota Tundra SR5. You will retain all of the functions your factory mirror had, but won't gain any that weren't there to begin with.

  • Towing Mirrors for a 2016 Toyota Tundra that Retain the Factory Blind Spot Detection System
  • I do have towing mirror options that will allow you to retain the factory blind spot detection system on your 2016 Toyota Tundra but the K-Source Custom Extendable Towing Mirrors part # KS70103-04T will not. Unfortunately, none of our replacement towing mirror options retain the factory blind spot detection system. Therefore, the only option I have for you is a clip-on towing mirror like the K-Source Universal Towing Mirrors part # KS3891-2. These are one of the only towing mirror options...

  • Is There a Difference Between K-Source Towing Mirrors for 2016 Toyota Tundra?
  • The only difference between the towing mirrors is that K-Source Custom Extendable Towing Mirror # KS70104T is for the driver's side of a 2016 Toyota Tundra while # KS70103T is for the passenger's side and # KS70103-04T allows you to purchase both at the same time as opposed to individually. These mirrors are a conformed fit for your 2016 Tundra and are power mirrors with heated glass and turn signals on the sides. I've added a link to a video review of the mirrors for you to take...

  • Best Towing Mirrors for 2018 Toyota Tundra
  • The best towing mirrors for your 2018 Toyota Tundra are the K-Source Custom Extendable Towing Mirrors # KS70103-04T because they simply replace the factory mirrors on your truck while allowing you to keep the turn signals, powered adjustment and heated glass features that are on your OEM mirrors (keep in mind these features will only be available if your current mirrors already have them). The K-Source Custom Extendable Towing Mirrors # KS70103-04T are telescoping so you will be able...

  • Will the K-Source Towing Mirrors # KS70103-04T Work with Lane Departure Alert for 2018 Toyota Tundra
  • The K-Source Custom Extendable Towing Mirrors # KS70103-04T that you referenced do carry over some of the electrical features that you have on your 2018 Toyota Tundra, but lane departure alert is not one of them. They are powered mirrors so that you don't have to open up your windows to adjust them. They also come with the ability to heat the glass and have amber lights on the side of the mirror for when your turn signal is activated. I have attached a review video for you to check...

  • Availability of Power Folding Towing Mirrors for 2008 Toyota Sequoia
  • We do have full replacement towing mirrors available for your 2008 Toyota Sequoia, such as the excellent K-Source Towing Mirrors # KS70103-04T, however they do not have a power folding feature. If your factory mirrors feature heated glass or turn signals then these will retain those functions but you will lose the power folding feature. This is the case with all of the replacement mirrors we have available. If you want to keep the power folding function then your only option is to go...

  • Will K-Source Towing Mirrors # KS70103-04T Fit 2019 Toyota Tundra
  • If the current mirrors you have on your 2019 Toyota Tundra have the ability to power adjust using the controls on the interior of your truck you have the power function which would also include the heat like what the part # KS70103-04T has. I wasn't able to find a version of your truck that had manual mirrors so these will fit and work well. Even if you didn't have the power functions the mirror would still fit and work great but you'd just not have the functions mentioned.

  • Towing Mirrors for a 2016 Toyota Tundra Limited
  • For your 2016 Toyota Tundra Limited you could use replacement mirrors # KS70103-04T but the slip-on mirrors are not designed to fit Limited or Platinum models. Another option is to use a universal mirror set such as # KS3990. I have linked video reviews of both mirror sets for you.

  • Towing Mirrors for a 2012 Toyota Tundra with Power and Heated Factory Mirrors
  • The 2 pairs of mirrors that we have with heat and electric functions also have turn signals. Even if your 2012 Toyota Tundra does not have turn signal mirrors, you can still use the K-Source mirrors, # KS70131-32T or # KS70103-04T. The other option are slip-on towing mirrors that fit on the factory mirrors, # CM11300. If your mirrors look like the one in the picture I have provided, these slip-on mirrors will fit.

  • Can Electric, Heated Towing Mirrors w/Turn Signals be Used if Factory Mirrors Do Not these Functions
  • The K-Source towing mirrors # KS70103-04T will fit your 2010 Toyota Tundra. Since your truck does not have heat or turn signals, those features will not work on the mirrors but the electric operation will still work. Another option is to go with some slip-on mirrors # CM11300. These are ideal for infrequent towing and are more cost effective than replacement mirrors.

  • Towing mirror set # KS70103-04T will fit your 2008 Toyota Tundra. They do have the electric operation.

I have linked a video review of these mirrors for you. We also have a set with a chrome finish, # KS70131-32T.

  • 2018 Toyota Tundra Blind Spot Monitor Towing Mirror Compatibility
  • From what I've found online you can disable the blind spot monitor with buttons on your dash. They will reset each time to start your vehicle, so you would have to do it each time you start your vehicle which would be quite the hassle when you stop for gas to remove your tow mirrors like # KS3990 just to start your vehicle and hit the button so you don't get the light. If you want to mount towing mirrors like the K-Source Custom Extendable Towing Mirrors - Electric/Heat w Turn Signal...

  • How to Determine if Towing Mirror Turn Signals will Work on a 2010 Toyota Tundra CrewMax SR5 4x4 V8
  • We have two towing mirror options for your 2010 Toyota Tundra, I provided links to both for you. The turn signal feature in these mirrors will only work if the connection on your Tundra is factory wired with a turn signal circuit. You can test the connector on your mirror before ordering to be sure that the turn signal function is present. To test the connection, use a circuit tester like part # 40376. Attach the alligator clip to a good ground, unplug the factory mirror and probe the...

  • Replacement Extendable Mirrors for 2007 Toyota Tundra
  • I am not sure what mirrors you currently have on your 2007 Toyota Tundra but if they are simply hanging off and you cannot get them to snap back in place they will need to be replaced as it is likely the tabs that hold it together are broken. I recommend checking out the K-Source Custom Extendable Towing Mirrors # KS70103-04T, which are a fit for your '07 Tundra and have power adjustability, heated glass, and turn signals (though those functions will only work if you had them on your...

  • K-Source towing mirror # KS70104T, and the set, # KS70103-04T, will retain the heat and power operation functions of the stock mirrors on your 2012 Toyota Tundra but you would not gain the turn signal function since the stock mirrors do not have that feature. The only way that you could get it to work for sure would be to tap into a turn signal circuit on the truck. But it theoretically could be done. I have linked a video review of the mirror set for you.

To check whether your truck is pre-wired for the turn signal function use a circuit tester, such as part # 40376, to test the connector pin for each mirror. If you do not have the turn signal function at the connector, then in order to have that functionality with the # KS70103-04T on your 2008 Tundra, you would have to manually re-wire your turn signals,...
