I know this is a common topic but I wanted people's opinions rather than advice on fixing it...

The driver's side headlight on my Discovery 1 (300tdi) has a lot of water beads inside - presumably condensation. It's been like this a long time.

I've pull the lamp off today and given it a wash out and it's now sitting on a radiator drying out so will see how it goes.

Generally, though, how successful have people found it fixing this problem? Was it wasted time? A new headlamp is only £25 and I can get a s/h one off of Ebay for a few quid.

Presumably it's the seal failed where the two halves of the lamp are bonded together. I was thinking of trying silicon sealant inside the rubber ring seal.

Glass to reflector seal failing then? and sealing will depend on the sealant that u use, u could use Vaseline with the rubber bulb seal.
Spend your few quid on e-bay is the easy fix I would have thought.

I've just had the exact same problem with mine, £10 for a s/h unit from my local landy place was the easiest option.

Thanks guys, I'll go the Ebay route and pickup a s/h unit I think.

I'll give it the silicon treatment while I'm waiting for the replacement to arrive - might be handy to keep as a spare.
