I've just noticed that one headlight is brighter than the other? The drivers (offside) has a more white-ish/yellowish tint where as the passenger (nearside) is more white/blue look?

I've only owned the car a few days so could the bulbs be mis-matched or could this be a sign of a bulb/ballast on its way out? It's the first time i've owned HID's, its all new to me so any info would be appreciated.

Thanks.

Have you checked the wirings connecting the the ballast? Might have a loose connection somewhere?

i tihnk ones meant to be dimmer than the other so you dont blind oncoming traffic..

my mates were dimmer on the offside like yours but not a different colour

never herd of one being dimmer, There just dipped to one side.

Sounds like the bulb or ballast might be on its way out, or the reflector part has some moisture or dirt on it.

I think this is the bulb as when first on they are the same colour then as they reach temp one fades..
