Shirley there are a few here...or at least some that stayed in a Holiday Inn last night...

Here's what I want to do:

I want to wire up some small LED lights under my rear bumper, but I want them wired a certain way...I basically want them on a 2-way switch where:

Position A = they automatically come on when the vehicle is shifted into reverse, and
Position B = manually turned on.

The reason being, I want them to always come on when reversing, but I want the option to turn them on even if the vehicle is in Park (like hooking up a trailer or something).

I called Truck Supply & Outfitters in Tuscaloosa a few years ago and they acted like this was simply not possible, so I gave up. But now that I've got a fancy new ride, I'd like to revisit it.

Surely it can't be that difficult.

Thoughts?
