The BEST Way To Wire Trailer Reverse Back-Up Lights

Here's how you can wire up LED flood lights to your car or utility trailer to turn on with the reverse lights OR the running lights, all using common off-the-shelf parts available online or at auto parts stores.

Super cool you put this together! This can ALSO become a safety feature of when you have to Change a tire ( off Highway, please ) at NIGHT. Great Job!

Thank you. Everything I had to figure out in a single video. Very informative and to the point.

Make sure you have a flat tire repair kit just in case you puncture the tire while drilling the fender...!!!!
LoL... I was yelling at you while watching your video...!!!
Close call drilling through the fender...
Great information on wiring the lights...

Great video, I watched this when I did my utility trailer lights 😂

Another thing to put on my trailer improvement list for both my 6x12 flat, 7x16 enclosed and my M101a2 3/4 ton military cargo (converted to pseudo single camper). The flat and 3/4 ton have 4 flats on the wiring so the wiring you show is extremely helpful. I am mechanically and electrically inclined, but I have to be shown or "steered" on how to do a particular thing along with sometimes why to do it that way. Thanks.

The 7 flat pin connection also has a 12volt accessory pin, red wire one i believe. You could just connect to it and wire add a small bus terminal that would then become a handy 12 volt supply for anything further you would like to add. You could switch control the entire terminal, or wire individual switches to different functions, such as rear lights, front lights, cargo lights, winch, battery charger, inverter, etc. Just don’t go too crazy and add too much! It will bog down your trucks power supply. If one wanted to add everything listed you’d have to add a battery, have it charged by the 12V accessory wire, then wire all the trailer accessories off the battery, or possibly have a voltage regulator in there as well.

Really good information and easy for everyone to understand I’m sure of it.

Question so I hooked up these lights to my truck and I tapped into the reverse wire on my 7 pin
I have aux switches inside the truck
I hooked up a led bar to front of truck can I run a wire splicing it with the front led running it to the rear and hooking it up so I can use it with the front led bar as well as with the reverse

[chevykev]

You nailed the need. Thanks for the share👍✌️

I have a switch like that on my car. So Every trailer and the extra back up Laps on my truck can come on by reverse or whit the switch

[Weird__Is__Natural]

Can I run my hots from the lights to the toggle switch then one hot from the switch to reverse circuit, the second hot from the switch to constant power (12v)? (My grounds ran to a 7 way junction box). I'm adding a 7 way junction and keeping them separate from my four way.

solder and shrink tubing is the best way to connect the wires.

You save me couple $'s thank you so much 🤝🏼

Great description. Thanks for your help.

[grutzmac]

Where did you pull the power from? How did you tap the tow vehicle for power?

[Blurredman]

A definite improvement... And.. scotch locks have their place in the world somewhere... :)

[brianvincent]

Did I miss where you tied in to the power circuit?

Hey, thanks for the video the drone shots from the top where it especially helpful. I think if you had mounted the lights at the Very end of the trailer the light would have been much better. 1/2 of the light is being shown onto the trailer and not the ground

Did you add
Positive from Reverse Lights to pin 1
Positive from Auxiliary lights to Pin 2 (Center)
Positive from tail lights to pin 3?

No Relay required?
