So I been going through fog lights left and right. No matter what brand I get it gets water behind the lense. And the weird thing is its only the passenger side one. Im about to say screw it and have no more fog lights. Ive bought $20 to $50 fogs. Anyone have any advise?

 

Use a high temp sealant on the seam between the lens and housing.

 

The Hella's on my XJ don't get moisture in them but I think they are about $150. Heck even the stock ones on my GC and Town Car do not either go figure.

 

I always drill a small drain hole on the bottom to let the condensation out. I put a piece of electrical tape over the hole if I have to ford a deep creek or mudhole.
