    Since fitting HID's i have had a gradual build up of condensation in the lights. Earlier today i took the units out and dried them out with a hairdryer. I used sealant to seal the black rubber grommet in the back plate of the unit for the wires to the ballast. I have now got condensation again and its driving me mad!!!

    Any Advice?

    Thanks

    Will

    The lights are vented, so sealing the rubber thing wont have made much difference.

    Audis answer (which may not work mind) is to run the main beam and headlights for 10mins while stationary to heat the light units up and dry them out.

    Will, as Aragorn suggested but try it for a bit longer. Next time you go for a half hour or so drive switch the headlights on and the heat should dry out the moisture. I had the same thing after I bought my car I had condensation in the headlight unit and realised that because i hadnt driven it at night and not had the lights on, the condense couldn't evaporate. I tried mine initially for ten mins or so but it didn'd clear, so then tried it for 30 mins and it cleared it completely. As long as you have no other faults with the unit, this should work. Well it worked for me anyway.

    Hope this helps,

    i have a new driver side dipped beam and a old main beam cover if you want one, bought it because the old cover was cracked and i haden't noticed that the headlight casing was cracked.

    pm me your address if you want it.
