Sure!!
I'd do pics... but I'm tired... and it's hot outside. LOL
I started with just some of the cheap Autozone driving / fog lights. They were $19.99. They came with a switch, and some wiring, mounting screws, etc.
Here's a Link @ Autozone..
I read somewhere that on the 7-point trailering harness, there was a reverse light connection in the middle pin. After taking a multimeter to it, I realized this was true! Tracing the pin wire to the light green wire that comes out of the harness, I tested the voltage on the wire. BINGO! I found a wire tap splice at Home Depot (they didn't have EXACTLY what I wanted, but a standard wire tap worked, I'd just have to rig up a disconnect (not necessary, however I wanted it to all be reversible.
Here's a picture... except, I used the blue (I think it's 18-14 AWG instead of 22-18)
If I could have found them, I wanted to use these:
Instead, I just made my own with a female connector and an extra piece of wire. (spliced the female connector and wire to the light green wire using the tap splice, then I had a disconnect)
Then, I connected the wiring to the lights (took out all the extra wiring for the switch as it was not needed. Something I want to do in the future: get a 3-way switch and re-wire it to be on with reverse, off, or on with the switch). These lights were wired as white and black. White is hot, black is ground. I could not find a good place for a ground, so I made my own. I used to be a garage door installer, so I had plenty of self-tapping screws. I used one of them and tapped into the chassis, and secured my ground.
The next part was the hardest part: Securing the lights to the bumper. I found a good place to mount them (equal distance from the trailer hitch... out of the way of the wiring harness) I started with the screws they supplied, however realized they were coarse threaded screws and probably wouldn't work in 1/8" thick (approx) metal. I tried anyway... stripped the phillips head... and ended up drilling it out. After that, I decided to go back to my garage door screws (they were made for metal, and had more fine threads). I drilled my pilot holes and ended up snapping the head off of the screw. Thankfully, there was enough head left over to secure it, so I just threw another one in a side hole to secure it... ended up breaking that head off too. Remember: When attaching to a bumper, use large enough pilot holes! After mounting the first one, I used what I had learned for the second one... drilled the right size pilot and fastened it without snapping any screws. I also mounted them facing a little outward so that I got better coverage. I mounted the lights.. plugged in the connectors to the right colored wire... and tested them. When I found they worked, I wireloomed and zip-tied them up ($.99 at Home depot for 3/8 wireloom 10') I found that if I aim them more straight than down, I get better coverage, and it doesn't blind you if you're standing behind it. It doesn't make it like my old off-road lights did, but it definitely helps. I can see back to my neighbor's garage... which that means I will be able to see anything behind me. If anyone has any questions, I'm more than happy to answer!
I found most of the information online. The ones I saw used a single 55w light... and I could see how that wouldn't work well, but the 2 lights @ 55w each works pretty good. Not bad for $25
Edit: I may include a "how to" in the technical write-ups section...
