HID question

[AdeV]

Yesterday, I drove for ~8 hours, most of the time with headlights on due to the stty weather.

I noticed, after maybe 5hrs solid driving, that one of my headlights was out. Mutter grumble, going to cost a fortune, etc. But when I moved the car later on, it was working again...?

I know almost nothing about HIDs, they came with the car; is this a sign I'm about to lose one permanently, or did it just overheat & shut down due to being on for so long? Or is it indicative of some other fault, e.g. loose wire?

TIA.

This was happening to mine too. I bought some cheap d2r burners from ebay. It has been fine ever since.

Ive had similar before on an audi with HID's and it was the ballast that was the problem, although in my case it was hit or miss whether it would come on in the first place, once on it was fine, eventually though it wouldnt come on at all and requied a new ballast, which wasnt sold separately so needed a complete new headlight!

HID's don't like being turned on before the car so when you start the car the go off then back on again. If you do this one often stays out. Just always start the car before putting the lights on.

One of my Xenons was going purpley pink a couple of weeks ago, then on Christmas Eve it went out. Like yours it did come back on, just for a few seconds but then died again. I ordered a replacement and fitted it last week and it's been ok since.

Normally, they come on before I start the car (I'm lazy & mostly use the auto feature). I've not noticed it being off again since that one incident (and since it wasn't fully dark then, it wasn't obvious it was out until I looked at it from outside the car.

I guess it's a case of keep an eye on it, and maybe buy a spare as a precaution. Is it worth doing both at the same time, or just the flakey one?

Cheers

If you only change one side then it probably won't look the same colour as the other, so unless you like the David Bowie look on a car, changing both is good!

I only changed the one side and they look the same.

David Bowie doesn't have different colour eyes, just one pupil is larger than the other

Running times shouldn't matter really, xenons produce less heat at the bulb than a halogen bulb

Probs is a doggy connection or bulb on the way out, change them both at the same time or they will be a difference in brightness.
