Headlight Gremlins.......

[shinkle]

I have 87 R10 with 4 headlight set up. Running lights/turn signals in the grille and running lights/turn signal on the outter front panels. The 2 upper lights are the dim and the 2 lower lights are high beams. All 4 are on when high beams are selected but only the top 2 when dim is selected. My issue:

Randomly my passenger turn signal arrow on the dash will glow greeen. When I turn the signal on it blinks really slow. Bigger problem is the passenger upper dim headlight goes out. Then out of no where the driver side upper will go out. Occassionaly no dim lights at all. If I turn on high beams all 4 lights work great. I never have any issue with the lower 2 high beam lights, turn signals in the grille or on the outter front panels. Only intermittent on off upper dim lights and the weird arrow glow slow blinker.

check your ground on each side. Might need cleaning up.

MIne did that, check your grounds just behind and above the light on the radiator support and the ground on the frame on the passenger side below the battery. Also make sure your headlight connections are shiny and clean. Fixed mine.

That would be the first thing I would check based on the symptoms described. Bad grounds cause unusual adventures.

Thanks all, especially Bedwards. I cleaned all the grounds and it seems to be working ok. Also discovered the plastic protective housing on the passenger low beam wires was broken. The brown wire and green wire would slightly push out of the clip when I tried connecting the wires to the bulb.
