Product is exactly as expected. Install was simple. All bolts line up with existing holes in vehicle frame. Ensure you apply the weather stripping on the mirror before install. Pictures and videos online are helpful. Side marker lights and turning signal works on mirrors. Great product! Attached are 3 photos.

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!

Outstanding!

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!

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.

Mirrors look good on truck easy to install. Only thing a is getting use to them over the stock mirrors. So far they seem durable didn’t have mirror maker lights before but with these mirrors my truck has them now.

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.

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.

Received K-Source Custom Extendable Towing Mirrors for my dark gray 2015 Tundra as expected. I had a bit of trouble getting the driver side OEM mirror removed as the center locating peg would not let go. Past that everything went together smoothly with only small adjustments to align the brackets with the door trim. Mirrors and lights worked as expected. Road test proved vision to sides and rear of trailer were greatly improved. Definitely, liked the addition of the blind spot mirrors...

No problems...working as expected...

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

Totally thrilled with these mirrors. Easy installation (the video was a great help) and they work great. Should have made this purchase years ago.

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.


Comments
After a year, still working perfectly. Extendable towing mirrors is something I should have had on all the trucks I ever ever used to tow anything bigger than a Jon boat.

One yer in and these mirrors work just fine. My only complaint is that they are very stiff to extend/retract, but so far it has not caused any difficulty.

Wow, just wow. Easy bolt on made life so much easier and safer. It's been a month or two and these mirrors have helped out immensely. Solid product, and I have the turn signals on the mirrors, heated mirrors and extra large viewing surface for when towing. Thaks to the CSR that helped me figure our the wiring and the correct model for my vehicle.

Have had great luck with these mirrors. Tried many slip on and clip on towing mirrors but none stayed put (several actually blew off going down the road). Finally bit the bullet and purchased these total replacement mirrors. They fit like the OEM mirrors.

The mirrors were delivered in 5 days, and look sharp! Installation was a breeze after watching YouTube videos. I am not a mechanic, and wouldn't have tackled installation had it not been for the videos. The only disappointment was finding out that the mirrors must be folded in manually (like to go through a car wash or other tight space). The original mirrors folded at the push of a button.

I just purchased these mirrors. Took 30 mins to install. Really simple. Happy with the purchase. I tow a 29ft travel trailer

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.

Where on youtube did you find the installation procedure?

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.

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.

Fit perfect and look great on my tundra. Side markers work even though my stock mirrors didn't have them. Excellent buy and shipping was incredibly fast. Very pleased

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.

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.

I really like my tow mirrors on my Tundra, nice to see what’s going on behind my boat when towing. Just a good quality product!

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.

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.
