I tried loosing the perch and waffling everything. The mirror light will go one and off while I wiggle the wires. I then tighten up everything again and when I apply the clutch the light goes back out as I squeeze on the clutch. As I release it the lights come back on. I just can't figure it out. Anyone have any other ideas what to look for? Like I said earlier, the lights work fine except when I apply the clutch. Then the left mirror (clutch side of course) goes out as I apply the clutch and then comes back on when I release it. Thanks....How do they ground?
Is it through the stem in which they mount on the clutch perch? so if so is the clutch perch move just enough to lose ground causing a short? Maybe try wiggling the perch with them on and not actually using the clutch to see if this is the case.
Might be as easy as taking off the perch and cleaning and reinstalling, or just a tighten up.
