I've got a couple of beacons and aux lights I'm planning on throwing on my squarebody and wanted to see how the people here have done it! If you've got a wrecker, road work truck or anything of the sort with spinny ambers, I want to see it!
I got the lights for my old gmt400 originally, but never got to installing them. All the same, the following picture is how I planned it and how I intend to install them on my burb:

Well the center aux's are going to be hella 550's instead of the jumbo 320's pictured, but anyway.

When wiring them, take power directly from the battery via a continuous duty solenoid, using heavy gauge wire. Size everything based on the total current draw of the lighting. This allows for a low amp switch inside the cab, while sending full power to the lights. This is how I used to wire tow trucks when lights were all incandescent. Lights will be nice and bright and spin at the proper speed. It's also safer, you won't have overheating wires.
