Sealing headlights

[mt308]

In the wet my headlights get very misted up, to the extent that water starts accumulating inside the covers. I don't think there is anything significant coming through from the front, I think its coming from the rear.

At the moment I have just the foam tape around the rear covers which gets pretty messy with dirt and rain.

I saw another Ultima who had sealed from the rear using a black silicone sealant which looked pretty neat. Downside presumably just that you need to cut the sealant to change a bulb, but that doesn't seem a big deal.

Anyone else got a solution?

Hi mark I did a similar idea on my noble but iff you grease the light cover then fit into the sealant it count stick to the grease forming a silicone gasket that you can take light cover of and on at leisure

Mark,

Check out these two links. One is information about putting flange around the back side light cover and the other one is prep for the slim line covers.

When the light cover flange was complete, I then used a an automotive caulk/putty to go in between the flange and the front clip. The seal is very good because the fiberglass flange formed to the under side of the front clip and dried.

Most of the problem is condensation so seal would have to be hermitic if you are going to solve it that way.
I just have the foam tape but have a PC processor fan fitted in each so it circulates air which removes most of the problem/

My lens covers arent sealed at all. they are easy to remove and clean, as i drive faster air goes in and out and cleans them. if they mist up, just turn on your head lights and the heat will get rid

Thanks all

Just looking at it again now having been playing around with heater valves, where there has been condensation it dries to leave a scale behind, so I definitely want to do something about it.

Not a massive priority, but I think the sealant with grease looks like a decent solution, the fibre glass moulding method looks like the "proper" solution if this fails.
