A towed car is required by law to have functional brake and signal lights that illuminate at the same time as the brake and signal lights on the RV that is towing it. Most wiring kits require you to splice into your vehicle's electrical system to install diodes, but doing this can void your manufacturer's warranty. You also run the risk of making a mistake during installation that could result in potentially damaging electrical feedback. Magnetic tow lights eliminate this problem because they bypass your car's electrical system entirely and leave your wiring intact. Just mount the lights on your vehicle's trunk or roof with the heavy-duty magnetic bases. Then run the wiring harness up to the front of your towed car, across your tow bar, and then connect it to the 4-way flat on your motor home or tow vehicle. If your tow vehicle doesn't have a 4-way, an adapter is required.


This kit includes a 20' long wishbone-style wiring harness with a 4-way flat connector on the end. A separate 3' wiring harness with a 4-way plug can be used to install a 4-way on your tow vehicle or RV if it does not already have a trailer connector. Quick-splice connectors are included if needed. A 4-1/2' long harness connects both lights, giving you enough slack to position the lights where you want them.

Video Transcript for Optronics Trailer Lights TL21RK Review

Today, we're going to review Part Number TL21RK. These are the Optronics Magnetic Mount Stop, Turn and Tail Towing Light Kit with the 20-foot Wiring Harness. This is a temporary magnetic towing light kit that includes the two stop and turn tail lights, the 20-foot trailer wiring harness and a stand-along three foot long four way vehicle-end connector, in case your vehicle doesnt have one. It comes with the quick connectors to attach the four-way to the vehicle if needed in the instructions. This does come with a limited three year warranty. Now, that warranty does exclude the bulbs.

It is magnetic mount, so you can just attach this to, if youre towing a vehicle, if youtr flat-towing the vehicle and you dont do it very much and you just need to use the lights a few times, you can use this magnetic mount. You can use it on the trailer if you have a trailer that doesnt have lights and you might need to use it at night. Basically, this magnetic mount, I have a piece of metal here. You can see it will attach to it and stays pretty firm to it. Its got a good pull to it, pretty hard to detach it.

You just put one of these on each side. The cord here is about four-foot, so they will spread out four-foot width. Now, I do want to show this does come with this 20-foot wiring harness. It has a trailer connector that where you plug into the vehicle-end four-way if your vehicle has one or if you attach this one to it. To give example of the brightness of the lights, I have a four-way vehicle-end connector attached to a power source.

Im going to give you an idea. Ill plug this in; we turn on the tail lights. This is what the tail lights would look like. Now, Im going turn off the overhead lights to give you an idea how bright they are in somewhat darkness. Then if you apply the brakes, as you can see, thats with the brakes and if we do a turn signal, I want to give you an idea of just the turn signal.

Thats how the turn signal would look like. Now, well go ahead and turn off or turn back on the overhead lights. That should do it for the review of the Part Number TL21RK. This is the Optronics Magnetic Mount Stop, Turn and Tail Towing Light Kit with the 20-foot Wiring Harness.

I am using these for added visibility on the back of a large bike rack that pretty much stays on the car all the time. I do not suggest using the magnets as the only form of attachment as they are not strong enough to keep the lights attached when going over bumps. I zip-tied them to the frame of the bike rack. At first, I had them sticking out from the bottom of the rack, and they were fine until I went up a steep hill and one of the lights got knocked off on the road. These lights are extremely well-built because instead of snapping the light, the rather large zip-ties broke. The light still works great after the incident. I now have them sticking out the sides to give more ground clearance, and they seem to be doing fine. For my application, I had to replace the wire between the lights with a longer one, but that was not difficult and will not be necessary in a typical application. At least the lights are easy to disassemble to access the wiring. The only way these could be improved would be to add strong neodymium magnets and to make the red lenses screw on (instead of snapping on) for easier access to the bulbs for replacement. Otherwise, a perfect product. For the record, I did not need to use the included vehicle wiring harness or splice connectors, since my application required an electronic light controller. 53035

I purchased a Curt hitch for my 09 CRV. I also bought a wiring harness and a set of magnetic lights for attachment to vehicles. I was able to install the hitch in less than an hour. It took me 30 minutes to connect the wiring. The lights are very simple to connect and only hook up one way. The instructions included links to videos that made the job a snap. The instructions said to put the wiring inside the car by the spare tire when not in use to preserve the connector. what a great suggestion! I did not put a single mark on the car and the hitch looks great. 29217

Perfect, just what we needed to get our trailer home from storage so I could work on the finding the root cause for the failure of the permanent trailer lights. Now that the permanent lights have been fixed, the temporary magnetic lights are stored with the trailer sort of like a spare tire, knowing how fiddly trailer wiring can sometimes be. It's worth the small investment for the extra measure of safety in case the permanent trailer lights fail again far from home. 82108

I needed to move a trailer to a location where I could troubleshoot and repair the trailer lights. Worked well, good price, and reasonable shipping cost, After I had used the lights I happened to see a similar setup at Walmart which was $10 MORE than the total I paid etrailer. 140114

  • Needed Items for Flat Towing 2012 Honda Fit
  • For starters, you will need a tow bar and base plates. The tow bar mounts into the receiver on your Winnebago, and would use the base plates that permanently attach to the Honda Fit as an attachment point. I would recommend the Roadmaster Falcon 2 Tow Bar, part # RM-520. The Falcon 2 is our best seller, and is easy to operate. The vehicle-specific base plate kit is part # 521190-1. I will link you to our video showing this kit being installed on a 2010 Honda Fit. Next, you will need...

  • How Strong are the Mounting Magnets on Optronics Towing Lights # TL21RK
  • Describing the strength of the magnets used on the Optronics Magnetic Mount Tail Lights would be fairly difficult, as magnet strength is pretty subjective. The magnet on one of the lamps is strong enough to suspend a 6 pound ball mount, as you can see by watching the short video I produced for you. Hopefully, this will give you an idea of how strong the magnet is. The thickness of the metal the magnetic light is attached to will also have a bearing on how well the magnet adheres...

  • What Would I Need to Flat Tow my 2005 Chevy Aveo
  • I did some checking and it looks like manual transmission 2005 Chevy Aveos can be flat towed without issue, but the automatic transmission Aveos can not be flat towed. You would have to check your owners manual to see if a tow dolly like a RoadMaster Tow Dolly with Electric Brakes, part # RM-2000-1 could be used. I attached installation instructions below for you to check out also. If you had a manual transmission you could use a RoadMaster Tracker Tow Bar - 5,000 lbs, part # RM-020,...

  • Adapting Roadmaster Base Plates to Reese Tow Bar for Flat Towing 2004 Jeep Liberty
  • To adapt the Reese tow bar to the Roadmaster 1422-1 base plates, you would need the Roadmaster Base Plate to Tow Ready Tow Bar Adapter, part # RM-025. In order for the removable draw bars on your base plates to function, you would also need the quick disconnects, part # RM-201. If you do not already have them, you will also need a wiring solution for your Liberty, safety cables and a supplemental braking system. If you are not planning on flat towing the Liberty very often, a magnetic...

  • Which Roadmaster Base Plate Kit Fits 1994 Honda Del Sol

This is the only base plate kit available from Roadmaster for your vehicle. Part # 508-8 will stick out a little past your front bumper to be able to hook to a tow bar. The 508-8 Base Plate Kit does not have removable draw bars and will be visible on your 1994 Honda Del Sol when it is not being towed. To complete...

Neither of these carriers fold up - actually, none of the carriers that will fit your vehicles 1-1/4 hitch and hitch rating fold up. Both carriers are basically the same dimensional size, weight capacity, weight rating, and price. Their exception lies in the construction of the railing. The # 6500...

Since you already have a tow bar, you would start with a base plate. Blue Ox does not offer a base plate kit that is compatible with a 2WD 4 door model Sidekick, but there is a Roadmaster Base Plate Kit, part # 1007-2 that will work, as long as your Sidekick...

  • Yes, the Carpod Walled, Folding Cargo Carrier # M2205-01-02 will fit your 2013 Ford Escape providing your trailer hitch has a 2 inch receiver. Personally, I would pick this one in a heartbeat if I still had kids at home and had to carry sporting equipment, backpacks or other odd shaped cargo. I also like the 5 inch shank rise, you can never have too much ground clearance. With that being said, the measurement from the center of the pin hole to where the shank begins to rise is 2-1/2...

  • Need Base Plates and Magnetic Tow Light Kit for 2007 Mini Cooper Convertible
  • I reviewed an online copy of the owners manual for the 2007 Mini Cooper. Page 114 indicates that the manual transmission model may be flat towed (with the gear shift in neutral) but that the automatic transmission version cannot be flat-towed without causing transmission damage. The automatic must be towed with the front wheels up off the ground as with a tow dolly like RoadMaster # RM-2000-1.

  • Parts Needed to Flat Tow a 1999 Ford F-350 with a 2005 Ford F-350

I would go with the Roadmaster kit because it uses removable arms for a less noticeable appearance when you are not towing. Keep in mind, the Roadmaster kit will only fit your truck if you have the front tie down loops. If you do not have the front tie down loops, then you will want to go with the Blue Ox kit.

  • Are Bulbs Included with the Magnetic Mount Stop, Turn and Tail Towing Light Kit # TL21RK
  • Yes, the bulbs are included in the Magnetic Mount Stop, Turn and Tail Towing Light Kit with 20 foot Wiring Harness, item # TL21RK. The statement, Limited 3-year warranty - excludes bulbs, is referring to the fact that the bulbs are not warranted for three years. If replacements are needed the Replacement Light Bulb # 2057, item # A2057B, is the correct part. You can gently pry the rear black plastic cover, on the back of the light, off with a small screwdriver.

  • Can the Wiring on Magnetic Mount Stop, Turn and Tail Towing Light Kit Be Extended
  • You can add additional wire if you need to on light kit # TL21RK. You can cut and splice in the appropriate length of bonded 4-wire, # 16-4B-1. It is sold in 1 foot increments so if you needed 10 feet you would enter 10 in the quantity box. And you can use butt connectors, # 05731-5, to make the splices. I do recommend wrapping the connections in electrical tape to further protect them. Another option that will not require cutting and splicing is to use extension loop # RM-300150-00....

You should also check with the owners manual of your Ford F-350 and see what the towing capacities of the vehicle are. At this point, I would seriously consider renting a trailer to haul your F-150.

The steering column should be unlocked by turning the ignition key to the OFF position, which is the next position from LOCK. The transmission should be in neutral.

A magnetic towing light kit like the Optronics Tow Bar Lights # TL21RK that you referenced should be able to provide any and all tail light functions when installed correctly. It sounds like the problem is in the trailer connector of your tow vehicle. Using the # 3808 you should test for voltage on the 4-way on all of the circuits to make sure that your vehicle is wire correctly....
