Wierd electrical gremlin..., possesed headlights... Options

[falcor75]

This last saturday I had been at an airfield slalom event and was driving home.
I've got Spokes front LED units so ordinary driving I just use the leds as DRL's so my lightswitch was in the first step pulled out.

Suddenly the headlights popped up about halfway up. (both)
I pulled the lightswitch out and they went fully up, I shut them down and they cycled down as normal.

Once back home in the garage I shut the car down and then turned the ignition on again and turned the headlights on, this time they kept cycling up down up down up down untill I shut them down. Tried it once more and this time they worked as normal... I tried to provoke the error again but only got normal operation.

Not quite sure what to think. Since its both the headlights thats affected I'm suspecting the light switch rather than a relay. What could cause it inside the switch I have no idea. (IMG:style_emoticons/default/blink.gif)

There's a relay on each motor so I doubt it's the relay since they both went up together.

When you had the up/down/up/down behavior, you said it continued until you "shut them down". Do you mean you pushed the headlight switch in? Then they acted normally?

Since they do this together, they're both getting the same signal. There's 2 wires from the headlights to power up (Grey; pin 56K on headlight switch) and power down (Green/Black; pin 30b on headlight switch).

I can get my headlights to go 1/2 way up if I pull the headlight switch then quickly push back to parking lights.

It seems like these 2 wires are somewhat crossed or shorting on something else.

It could be your switch as well. I don't have any experience with failing headlight switches. Maybe someone else will chime in.
