Car Headlight

RenegadeRick

98th percentile on my SAT & all I got was this tin
Since the major use for my car is to drive me and my bike to the trails, I suppose this qualifies as a biking technical question.

I have a 2001 Subaru Forester and the left front headlight on my car keeps going out. It is a dual filament bulb with integrated highbeam. The highbeam doesn't keep blowing, just the low beam. I have replaced this bulb 3 times this summer and this morning I noticed it was out again. I'm starting to get kinda pi$$ed.

At $10 each they are not cheap and sure, I could probably get a better deal buying in bulk, but I would rather figure out the root problem.

Any ideas?

My 96 Landcrusier has the same problem. The headlight somehow lets moisture in, and fvcks up the bulb. Mine takes about 2 months to go, shorter is it rains alot.

I am going to try a dessicant in there (you know the packets of moisture absorbing material in Beef Jerky and electronics) see if that helps.

I didnt do this, because it's a bitch to get the h/l out of my truck, but take the h/l out and plug the hole with clay or something and submerge the h/l. then seal where the bubbles come out...

Just my .02

Peace,
Marc

Do you notice any damage to the bulb when you pull it out? Halogens run right at the edge of being too hot so any little bit of contamination will overheat them. That's why it says not to touch the bulb. Oils from your skin will cause them to overheat, even blister the glass bulb if it gets hot enough.

I use nitrile gloves when installing mine. Not ruling out some electrical glitch but have you tried a different brand of bulb?
