I fitted a xenon upgrade kit (stealth from hids4u) last year. On the way to work today I noticed when I was sat in traffic that one of my headlights was out (reflection from the nicely polished car in front). I know nothing about xenon bulbs or what lifespan they have. I have ordered a replacement bulb as they are only £9 and it’s a good place to start. I haven’t had a chance to fault find yet but has anyone had any issues with the kit or is there a list of common faults? I can’t find much as I believe they are fairly bullet proof. Hopefully it’s just the bulb (probably not helped by hitting a deer the other week… again).

That wouldn't help!🫎

Mine have been fine since installed 3.5 years ago.

Did you get the replacement bulb from HIDS4U ? Jules

Yes. I wanted to make sure it was the same colour (5500k in my case).

Thanks for the replies. Just looks like I was unlucky. If this one blows then I’ll take a look at the ballast. Still, it’s far better than the halogens!

I have found Stealth as a company very helpful

Now I’ve just purchased a bulb the light has started working. That’s my weekend cleaning connectors, looking for loose connections or broken wires. I just hope it’s not the ballast overheating. Its currently inside the headlight unit so doesn’t get much ventilation.

I had a Stealth HID intermittently not working (from startup, so not overheating) and it proved to be the ballast. Easy way to tell is to swap the bulbs side to side whilst leaving the ballasts where they are, then if it happens again the side which is out will show you where the problem is.

I purchased the Hb3 stealth-x as it matched the temperature colour of my original, 5500k.

I had a ballast unit fail on one of my ABD conversions, you can buy replacement ballast unit on its own from ABD. Easy to check by swapping a lamp from the good side, if the good lamp doesn't work then you know the ballast unit has failed.
