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?
