The pic was on the page that I linked to on taillightking <dot> com. Looks like the center screw connects to a terminal on the end of the hot wire. And the outer screw connects to ground. Call the guys at "taillight" and at "unity" to discuss and find a 12v substitute.

Not sure if hi-beam sealed beam quad headlight were 5-1/2" diam or 5-3/4" diam. It's not ideal, but you might be able to use push-on spade terminals to adapt one to your spotlight if there is enough space in the housing. Watch for high current draw.
