OK ... here goes. You are correct ... the set up on these is direct wired to the battery. There is no allowance to render them inoperable with the ignition off. I'm sure someone much cleverer than myself could rig them to do that. The places I generally travel, this is not a great concern. Should it become such on a rare occasion, I would simply reach underneath the switch and pull one of the wires off. I mounted the switch on one of BWC's fancy schmancy dash thingys, which he was kind enough to send me. Highly recommended for stuff like this. He does a beautiful job and it was a perfect fit. I painted mine red. He primes them so you can do whatever.
Here are some pics. They are Rigid Industries Dually lights. 1300 lumens, 15 watts. Bright little suckers. Metal housing. Some 1" crash bar mounts. I had to adapt a bit as the bolt attached to the light was 5/16", and the slot in the mounts was 1/4". The light is set up for a carriage bolt. But the head of a 1/4" carriage bolt is too small for the light and rotates around in the light mount slot. So I bought some good quality 1/4" bolts, washers and lock washers. It aint' all that purty, but it's one solid sucker.
Please, no snickering. I've never done anything like this before on my on. I'm always had talented help with most of my projects. I'm a fish biologist, not a creative, ingenious, mechanical type of guy. I'm a bit of a numbnuts in that department, as you likely have already figured out.
I don't even know if they are in a good spot ... I wanted them on the crash bars, so I was limited. I moved them to the inside a bit so that in case of a whammy, they should not receive the brunt of the pavement/gravel contact.
