Leaking Fog Lite

Have pretty much narrowed my moisture problem down to the O ring seal, have applied more sealant to the actual lens body face so now I need to ask for some ideas on how to enhance the sealing at the point where the O ring meets the housing. So far some have suggested to grease the O ring before installing the lamp. Open to advice,perhaps the grease type,fire away!!

 

Use dielectric grease, it's silicone grease and not only it preserves the o-ring but it also seals out moisture.

 

Right on. Thank you

 

Well took everything apart,dried it,and used the dielectric grease. Today I c a small condensation forming again on the inside of lense?? Not sure what to think of this,raining steady here . Anyone got a suggestion? Try another lamp maybe. Just thinking someone may have experienced this and conquered it. Thanks

 

Top up the halogen fluid and you won't have another issue.

Seriously though, are you very sure the light was totally dry inside before reinstalling? It doesn't take much moisture to fog up a light.

My only other suggestion would be to remove the bulb, then fill it half full of water, reinstall the plug and see where the water leaks out. Mark the spot with a felt marker, dry it completely and repair the leak.

 

I dried the lamp housing overnite above a wood stove,so no chance of left over water! I like the idea of half filling,sure not much else I can think of. Wait and c for any other ideas while the rain pours down,no shop to work in. Thanks a bunch

 

It's most likely the seal around the lens itself and not the bulb. You're gonna need to bake it, take the lens off and re-seal.

 

Filled with water,could not c any leakeage. Glue gunned the lens to housing surface,siliconed around the lamp to housing area,plugged breather hole. Will leave light off and c if moisture still forms???
