Should have mentioned that. I've changed the bulbs as well and it's made no difference, both still functioning perfect when just the ignition switched on but once I start the engine the drivers side goes out.

Hopefully someone can help with this one. Factory xenon lights in an Is250 sport, 06 reg with 63k. When ignition is switched on the lights function fine. Once the car is started the drivers side light goes out. Any help is greatly appreciated.
