Yes, I know its a well discussed problem for LRs but really, is there a way to alleviate this annoying problem. The offside headlight has come out more times than a day time TV announcer. I have dried it, taken out the vents at the rear and cleared out the filters, drilled drain holes in the bottom front, tried 0.5mm vent holes at the top of the lens, changed the seals on the bulb access ports, just about everything and still it fills with water.

Dont get me wrong this is not a mud plugging submersible S2D more a swanny down the pub with a few mates and the old dog type car.

The nearside (same age as the car: 2003) is perfect.

So any suggestions apart from get another lamp assembly, would be greatly appreciated?

Many thanks in advance

Bake in oven for 5-10 minutes.
Lowest setting is usually 350 F, and 200 F is all you need.
So, put light housing in oven, turn on, and check often.
Point is, to soften the plastic, so that the clips/tabs that hold it together get soft, instead of brittle.
Then, you can easily open/seperate the pieces. Do this quickly, as it will cool fast.
Once apart, clean it well. Reassemble using clear silicone. Carefully and sparingly, otherwise the silicone will push out of the grooves to the inside, where you can't wipe it off, and it'll be an eyesore.
I'de fill any vent or drain holes too.
I have done this, and seen it done sucessfully on cars and bikes. My 04 D2 passenger headlight needs done also. I'll post pictures whenever I get around to it.
I only have 10 other things that need fixed on it at the moment, lol.
Good luck with it, it isn't hard to fix.

 

Thank you for your advise. Maybe that is the secret: remove all moisture and re-seal.

In the past I have used a hot air gun (lowest setting) and passed warm air through the lamp assembly (without splitting it apart) to dry out then reassembled using vent plugs at rear and a drain hole in the front. I am beginning to think that if this allows cold, damp air into the assembly then condensation is bound to form. Maybe the secret is to seal all orifices after completely drying, with silicon sealant, that way the dry air will be trapped inside and condensation cannot form.

I really should like to know LR design philosophy as to these assemblies especially regarding the vents at the rear. Do other car headlamp assemblies have them?

My D2's headlight condensation got worse, there was a small water reservoir building up already. To bake them in the oven in order to remove the lens sounded too risky to me. I watched a video on youtube and this method looked quite brutal. I just removed all the bulb covers, put the assembly with the lens down on a radiator heater. After a few hours all the water and moisture was gone completely. Cleaned the gap between the lens and the housing with a toothbrush, squeezed a bead of clear silicon into the gap, also sealed the clip areas on the sides. While letting the silicon cure, I cleaned the gaskets of the bulb covers with silicon oil and the mating surfaces. Finally let it dry over night on a warm surface again, before attaching the covers the next morning and installing the assemblies back to the D2. So far it looks great, no fog on the lens anymore. I hope it lasts.

 

The oven is risky, too hot and you melt/warp it. I like to put them on the dash with the truck parked in the sun facing west. The windshield heat (at least in the south) will quickly dry out the housing. I do it with the bulbs out, lens down, so the water evaporates out and up.

 

I have water/condensation on my passenger turn signal. The problem I’m having is that water is coming down inside of the wire loom for the headlight, I have no idea where it’s coming from.

 

You can fill in the hole in the headlight the harness goes through with clear silicone.
