I found this terrific trailer hitch light that you simply plug into a 7pin trailer hitch. It has two settings where you can use it as an utility light or as a backup light. It projects a 50watt halogen light, and lights up pretty well!! I used mine for a couple of weeks and love it.

I recently found a few of these discounted at Target stores, and bought a few. The one I bought at Target was $29.99 and I've checked online and that's the going rate.

I've listed this Light Buster Trailer Hitch Light here in case you are interested. Thanks for looking!!

looks like a piece of ****

 

A better option might be an "EZAux" adapter that turns YOUR lights on and off? The 7-way plug on my truck points right-to-left so a plug-in-flashlight wouldn't do me any good.

I bought a $25 set of 'driving lights' at Wal-Mart and mounted them under the bumper then connected ONE wire and I was done! (my lights are grounded to the frame so i didn't need the ezaux ground wire)

EZAux turns my lights on when I put my truck in reverse ... and there is a built in switch so I can turn them on manually like work lights.

Checkout http://www.ezaux.com for more info... I'm really happy with how easy it was to add GOOD backup lights!
