Hi guys any body refurbed their headlights to still find they end up with condensation inside. Took mine apart painted the plastic put back together with sealent used by bae in afterburners so that's shouldn't be a problem. Anyone else had same problem or lives close to hull to have a look incase I'm been blind.

Could be the bulb holders not sealing properly. Any gap in the light can let moisture in. Either that, or when you sealed them together, there may have been moisture in there already, in which case it could be evaporating and condensing within the light.

 

Have you tried removing the light, putting it somewhere warm and dry (airing cupboard for example) over night, then reinstalling it?

Ensuring the bulbs seal in properly.

Yer its in the boiler cupboard now so hopefully it will dry out in next couple of days and ill go round the join with some more sealant. I did drivers side at same time and that one is fine.

 

Just keep in mind that if you take the headlight straight from somewhere warm (ie house / airing cupboard) and put it somewhere cold (ie outside) this can cause condensation on the inside because of the temp difference between the air on the inside of the light and the air outside of the light.

This will take a day or so to settle as the warm air leaves the inside of the light via the ventalation tubes on the back of the light. (This is weather dependant)

Am I better off letting in dry out then putting in inside the car for few days so it gets down to temperature before refitting it

 

Dry them out indoor, make sure you are happy with the seal around them, check for holes, gaps etc.

Once happy and lights have dried out, if you are able to place somewhere cooler to let the temps balance this helps stop 'insta'-condensation. Inside the car would probably work as will be cooler than inside the house but not as cold as directly outside, garage another possibility, shed?

Either this or fit them on a warm sunny day with the car in the sunlight, the lights can adapt as the weather goes off then. (Not many warm sunny days atm though >

I had mega problems with this and it turned out that the plastic cap on the back of the fog lights were missing. Do you have HIDs?

 

Other than that there must be a sealing problem. The lights are designed to "breathe". I doubt you haven't sealed them properly if there is a lot of moisture in there then it is coming from somewhere else.
