Does anyone have ideas on troubleshooting PIAA driving lights? I don't know the model of my lights but they have a metal housing and glass lenses. The control is a little oval push button and signal light. I've checked the fuse and ground and both are good. I tried to trace the wiring but it was very professionally installed. It's taped, tied and hidden in the harness under the tank (just like a factory mess). Before I go cutting the ties it would be nice to know what I should be looking for. Any suggestions or advice would be greatly appreciated.
