water in headlamps
jlparsons - 15/2/09 at 11:13 AM

I have a BMW E90 headlight unit that's got condensation in it due to a not-very-speedy swap-over of bulbs. It's a twin reflector unit with both bulbs occupying the same void. I tried leaving one bulb out to open it to the air and running engine with full beam on - this made it nice and warm and got rid of most of it but there's still a little condensation in the far corners.

Any good tips to get it out? Otherwise I'm going to have to either get me some dessicant or resort to piping a hairdrier through one bulb hole and out the other. I'd really rather not take out the whole light unit if possible.

Take the bulbs out and use a hot air gun to heat the glass . Be careful you dont get it too hot . Works for me.

a hair dryer would be a bit safer

Oh I dunno - i've heard a lot of people on here have a BEC.

borrow your wife / girlfriends. If you can't post on here about a BEC meet at your house and i'm sure 2 or 3 will turn up.

I dont know how well it works but heard people saying sica gel ball packets like you get with new shoes can be taped to the inside and will absorb the moisture

Will try that after the hairdrier, thanks. Someone said I should try to get some from a glazier, apparently they use that stuff when they put together double glazing panels.
