why would this happen? Its was a brand new GM HID unit fitted by myself. No damage at all, its only 5 months old but shows heavy water droplets to within an inch of the top inside the glass/plastic.

The rear rubber covers are fitted correctly afaict without removing the battery(pass side unit). Ironicly the drivers side rear rubber has come adrift, but no damp.

I'm now a bit concerned that there will be damp in the electrics and residue left on the inside of the glass if or when is dries out.
 
Most bike head lights have little vents to allow it to breath, dont recall anything similar on these items?

Any ideas?

Cheers

Chris. :-)

the unit should have a hole in the bottem when new has a rubber plug in it.

I'll have a look at my old ones if you like, I still have them.

I always seem to have this problem on every car I get including brand new ones

That would be great, just to confirm, thanks.

I used a hairdryer (a hot one) a short while ago on the outside and the condensation went away.

UNFORTUNATELY, being an idjut I didn't remove a bulb, not knowing about said plug either, and the condenstaion came back. Hopefully if the hot air inside the headlight, caused by the hairdyer had somewhere to vent out then the condensation my stay away a bit longer...ANOTHER job for me to do.

I've got them out and to be honest I cannot see any purpose made breathing vents. Now there is a small hole just behind the indicator but the hole does not make it beyond the reflector. Is the condensation occuring in the outer corners?

No, its seems to rise and fall, like a tide mark, in a horizontal/level line, only the top inch or so is clear.
Strange :-(

Thanks for looking though. Saves me removing it for no reason.

The front lens just seems to far isolated, I mean why shouldn't condensation form on the reflector for example. Could it be that the lens isn't properly sealed or maybe some of the moisture in the gunk has penetrated the unit?

I fitted my DEPOs in August and they seem fine so far. Have you considered raising the issue with vauxhall? Are they actually Hella units or GM?

I have a bit of condensation in my headlights, but not a lot.

 An idea I had, though not tried it yet is to put one or two of them small sachets of silica gel in the headlight, maybe with a bit of string attached like a tea bag so it can be retrieved to dry in the oven occasionally.
 They put this stuff in the gap in double glazed windows as it soaks up moisture and holds it, thereby needing to be dried in the oven now and again, with double glazed units no need to do this as they are sealed from the air.

dont turns lens yellow, my depo,s have a rubber on like i said on the bottom, when got them it had a sticker over the hole said remove sticker and plug before fitting.

[Ken L]

Thats interesting! I wonder why that is, as it doesn't affect windows in that way, they stay clear, the gel is not supposed to release anything, you find it inside camera's for example with an internal mirror etc. Well in the box anyway.

I think I will try this out with an old headlight I have in the shed. Over what period of time does the effect take?

[feeutfo]

i wouldn't worry Ken tbh.
There is no hole/plug/bung on the bottom of the Depo lights either.
