My friend's 2002 RSX has had quite a few burnt out bulbs in the past
year. First, the right blub died after about 3-4 years. Next, the left
bulb died after a couple months afterwards. Then the right bulb died
again after less than 1 year (I think it was a generic non-Acura bulb).
Does 3-4 years seem kind of short for a factory bulb lifetime? I
definitely know that 1 year is way too short for any bulb. How long
should typical bulbs last? My friend is in northern California, so the
weather shouldn't be the cause. Could their be some other causes
besides bad luck?
Four main causes:
1) Overvoltage condition due to alternator defect;
2) Headlights being used all the time as though they were DRLs when they
3) Vibration due to incorrect installation;
4) Aftermarket bulbs, especially "ultra-bright" or "blue" bulbs.
Check the failed bulbs. Do the ends of the filaments look melted or just
Yes, unless your friend is one of those people that drives around with his
headlights on all the time, in which case it's normal for bulbs that were't
designed for that.
Some aftermarket units last less than that.
Well, I replaced my original OEM Stanley bulbs in my '91 Integra last year.
I'd say 14 years is pretty good, wouldn't you?
Also replacing/handling the halogen bulbs without using gloves or other
means to keep skin oils off the quartz envelope will shorten their life.
"wiping" them off after installation does not work,you need to use alcohol.
