I was thinking I could replace the chubby hole with a steel plate and then mount these on the plate. I think I could get three switches in that location. different color LED for each aux light. I would try and paint the plate to match as much as possible.
Basically just soldered wires from the lights to the thing that clips onto a 9 volt battery, which you can get at radio shack for like $2 a dozen. And you'll have to put a toggle switch between the lights and the battery on one of the wires. The toggles run about 3 for $4 on amazon.
