CaddyChris Posted October 22, 2005 Report Share Posted October 22, 2005 Hey all, I have water in one of my foglights, I don't know when it started but I noticed the light was out and looked at it today and it has about an inch of water in it. I guess this is why it's out. SHould I just drill a hole in the bottom of it similiar to the fix for the rear tail lights. I have one in the rear that is showing condensation. Maybe if it is nice tommorow I'll attempt to fix them both with drilling holes unless someone has better suggestions. THanks.

DADCAD Posted October 22, 2005 Report Share Posted October 22, 2005 I am going to do the same Sun. Afternoon...I have a set of 1986 Mercedes 300SD fogs in my grill...the right side collects condinsation...I am going to drill the bottom and a small hole in the top...touchy though..they are glass. I willhave to be very easy with the dremel tool...Should work for both of us I would think...Good luck Link to comment Share on other sites More sharing options...
Scotty Posted October 22, 2005 Report Share Posted October 22, 2005 Before I drilled holes I would check to see if there is a crack in the lens or a seal has begun to leak and fix that. The hole will allow dirt and fine moisture to enter the lens and it will always be cloudy. Link to comment Share on other sites More sharing options...
TDK Posted October 22, 2005 Report Share Posted October 22, 2005 Hey folks, Why not drain the water out of the lens, purge the moisture-laden air out with nitrogen and then seal it shut? Insert a basketball/football inflation tip through a tiny hole or seam and have the professional tire shop CAREFULLY add some nitrogen. It would be bad to explode the lens assembly, so the inflation tip hole has to have some play in it - to let the air out as nitrogen is added. The needle tip just has to protrude about an inch or so, not all the way to the back side. The objective is to simply displace the air. The lens does not have to be "pressurized", just enough nitrogen to "blanket-out" the air and then tape the hole shut with some metal tape. A few granules of dried silica/alumina gel (the do not eat stuff packed with electronics) might also adsorb some moisture (and regenerate/dry-out when the bulb is on, via the vent hole), but this is a bit more messy. Good luck! Good luck Add power to leave problems behind. Most braking is just - poor planning. Link to comment Share on other sites More sharing options...

The hole will allow dirt and fine moisture to enter the lens and it will always be cloudy. Guaranteed... Water in the Fog Light = Crack... If you're cheap: Remove the light, epoxy the crack and replace... Or: Buy a new housing from the dealer and replace... $$$ Fog lights are very vulnerable on our cars... Cracks can be easily caused by curbs, rocks, snow, ice, or just plain old age.. I even seen them crack from immersion into deep puddles... Sudden massive changes in temperature is hard even on plastic... I like the Nitrogen Idea! Argon would work better as it is more inert and is a better insulator... You could use Helium too... This would make your car lighter and therefore faster! But it might make your engine sound like daffy duck!

CaddyChris Posted October 24, 2005 Author Report Share Posted October 24, 2005 Hey All, Thanks for all the replies. It was such a productive weekend that I never glanced at the light. I will take it off and inspect it and if it is cracked I will most likely try and seal it depending on where it is cracked. When I do this I will let you know what I came up with. I like the nitrogen idea too but I am not that motivated. Also, I did a search for fog light and it looks like there are some pretty good ideas for replacement bulbs that I may look into. Thanks again Chris Christopher Petro 94 sts 67 coupe de Ville Link to comment Share on other sites More sharing options...

CaddyChris Posted November 17, 2005 Author Report Share Posted November 17, 2005 I had the car up on stands last weekend to change the oil and I figured while it was up there I would take a look at the light.... Well, I took it off and dumped all the water out of it. The bulb was cooked and melted.... anyway, there was a tiny crack right by the bulb housing and also when I was blowing air in the light I saw bubbles comming out of the bottom of the lens assembly where it is sealed together. I dried it really well and put some sealant over the crack and on the seal where the lense it squeezed together. I also buffed the front of the lense with some plastic buff. It was in pretty bad shape. Than to top it all off I was going to mount the bracket first then put the light back into the bracket with the plastic clips(i took the whole bracket off to take it off). I thought this would be easier , well, in order to get the light out of the bracket you have to mess with the adjustment and unscrew it. Well, when I started to unscrew it...CRACK... the plastic that held the bottom of the adjustment screw from turning broke. It still was intact enough to maintain it's structural integrity so I left it alone and put the whole bracket up with the light. I was pissed but it worked out ok. 11 years on plastic makes it pretty brittle...plus the screw was not lubed either.... Anyway it poored last nite and this morning the light was dry! success!....almost(the broken adjustment upset me, but oh well, i m not paying for a new one).
