installation was easy lights appear to be bright enough. Only negative I will say is the main wiring harness could be longer so It would reach to the front of all full size pickups. I have A 2026 Ram 2500 with 6.4' bed and I would have preferred another foot of wire. I installed light right under factory lights.

Attached the lights to my camper shell on our toad and tied them into my motor home wiring. Worked well and did not have to tie into the truck wiring system.

Have not used it yet but installed and looks good. This avoids any disruption to vehicle electrical system. Shipping was very prompt however mail to Canada was extremely slow through no fault of etrailer.

I like the lights, they are bright and bypass the electrical system on the new truck. The cable was too short for a full sized pickup and I had to wire in a 4 foot extension. Also the terminal blacks that came with the system don't hold the wires securely so I used Butt end connectors to insure a secure connection. Am happy with the finished product with the changes.

Excellent product. Easy to install and works as advertised. These lights do not use the tow vehicles wiring system which eliminates the need to purchase diodes. Looks af works great. I will definitely use eYrailer again.

view full answer... - Which Roadmaster Base Plate Kit Fits 2026 Chevy Tahoe Z71Hey Kevin! It looks like Roadmaster recently updated their fitguide, and the only base plate kit that fits your 2026 Tahoe Z71 is the # RM64ZR so that is what you need. We haven't had anyone bring their vehicle in for installation, so we don't have a video or any pictures right now. The only picture is the one I attached below from the Roadmaster installation instructions. Also, this is compatible with your Nighthawk. It looks like diode kits aren't an option so for lighting I recommend...

The Brake Buddy Select 3 Portable Flat Tow Brake System # HM39524 is also compatible. Do you have everything from the original setup for it? If not, you probably need the Second Vehicle Kit for Brake Buddy Flat Tow Brake Systems # BB59SR. The Brake Buddy includes a charge line, the 2nd vehicle kit replaces that if it was left on the old vehicle, so the # RM-156-25...

view full answer... - Tow Bar, Wiring, and Supplemental Brake System for 2024/2025 Lincoln NautilusHi Barry; the only base plate kit for the 2024/25 Nautilus is the Blue Ox Base Plate Kit # BLU35UR which is designed to fit the hybrid model. According to the owner's manual, you cannot flat tow your Nautilus unless it is the hybrid. If you have the regular gas engine model the only option is to use a trailer. Assuming you have the hybrid I recommend the following for a complete setup: -Blue Ox Base Plate Kit # BLU35UR -Blue Ox Avail Non-Binding Tow Bar # BX7420 (includes safety cables) -Roadmaster...
view full answer... - Is The Roadmaster LED Strip Light Wiring Kit For Towed Vehicles Street Legal And Easy To See Yes, the Roadmaster Universal Wiring Kit for Towed Vehicles # RM35MR would be acceptable in a flat towing capacity to display your motorhome's light signals through your 2023 Ford Maverick's tail lights. They are only 10" in length with a single line of LED's, so while they would bright it would be just a simple strip of light instead of your typical square or round tail light design like the # TL21RK. In your situation magnetic lights aren't as easy of an option due to the limited mounting...

Yes, the Blue Ox Base Plate Kit # BLU96ER is the correct unit for your 2026 GMC Yukon XL AT4. I went ahead and double checked with Blue Ox, and they said it is compatible with the diesel engine as well. Just make sure your vehicle has the top shutters only, If you have the lower shutters there are no base plates that will fit at this time.
