I have an intermittent problem with my Xenons.
When I get in the car, turn the engine on, then switch the headlights on after a few seconds BOTH xenons switch off at exactly the same time.
It happened yesterday when the car was cold in the evening. Got in switched on they came to life, and then went off, I switched off the headlights switched them back on after a few seconds and they worked fine.
Tonight, they went off, I switched them off and back on and they came back. I pulled away and got up to about 15 mph and they went off again. I pulled over and switched the switch off and it took a good 15-20 seconds before they'd power up again.
It's an intermittent problem so I can't test it easily.
Is this a problem anyone has seen before?
Each side is fused independently and the fuses are ok. Are there any common electrical circuits or control systems that would affect both lights at once?
The bulb out warning(s) did NOT come on.
Are there any relays that might go bad or could it be the headlight switch itself?
