Quoted from futurepinhead:Okay give me some ideas to get my topper to work.
There's a seperate PCB inside the head (top left) that drives those lights. I'd check input and output voltages first. The bulbs are #194 or #161 (12v bulbs). If it has 555's up there they will blow fast.
If none of that works, I think there are two transistors that drive the circuit, so you would have to begin backtracking to those.
