Here they are! A last-minute mod before the Borrego trip.
The lights are Daystar #KU80002 lights, 55-watt halogens, and are super-cheap, made even cheaper by the fact that I got them for $20 for 2 from Craigslist.
I mounted them into existing holes on the bumper support, and the simply had a threaded stud that mated with a nut and lock washer on the other side.
Because of the slope of the bumper support, I had to use washers to space the lights away enough to aim them sufficiently upward to provide the desired lighting angle.
They're currently wired through a relay to a toggle switch in a temporary location near the pedals.
All wiring on the lights is covered with heatshrink, and the wiring going into the engine compartment is covered in wiring loom as well.
