1995 Legacy Outback fog lamps - cleaning ideas?
Posted: Tue Mar 11, 2003 8:30 pm
Hello all. I'm new here, this being my first post. I own a 1995 Legacy Outback - you know, the Outback that's almost an Outback. I've been driving the car now for 2.5 years and love it. It's going strong at 128k miles and will be 100% paid off in 6.5 months.
The vehicle is outfitted with small fog lamps, made by Koito; they use H3 12v 55w bulbs. A pic can be seen here: http://38.181.236.4/~bsullivan/auto/199 ... utback.jpg Some of the markings on the housing are US 491, Japan >PET-GF30<, KOITO 114-20585, SAE PET-GF30, H3 12V55W.
Neither of the lamps are working- I removed them last night. The R one has a burned out bulb (simple replacement; done) and the L one is, well...
. Along the line someone replaced a bulb in this unit and did not screw the rear cap back on properly; one of the three tabs was unseated and water seeped in. I assume the bulb subsequently popped or something, with the water seeping in and out, because when I opened the rear cap up, the entire thing was coated with a white powder and lots of corrosion. The worst thing is that the glass lenses inside are coated with this sort of 'baked-on' white powder. The unit is sealed (silicone seal between the glass front piece and the rear plastic piece - I can't get it apart) and the glass surfaces inside are inaccesable.
My question is this - can anyone recommend an industrial strength cleaner or some unusual process that I might try to clean this white coating off of the internal glass surfaces? Again, the real problem is that I can't get at it to scrub it. I swished hot soapy water in it all last night and removed about 20% of the grime. I am looking to keep the costs as low as possible, with the ultimate outcome possibly replacing the unit itself (This may be the best route). I visited Advance Auto Parts last night and checked out a new set of Hella lamps at $60. This is way over the amount I'm willing to spend right now.
One might ask why I didn't do this earlier when the lamp wasn't so fogged up? Well, I've only recently become interested in upgrading / caring for my car, and now I'm crazy about it. I don't have a LOT of mechanical experience, but I'm learning. I love this BBS and reading the posts is great! My work productivitiy is headed down the tubes, but I'm learning lots about my Subaru!
THANKS
