I've got a problem with my headlights being rather dim, up to the point where they're almost non-existent. My car's a 1999 Camry CE, i've got the original lightbulbs, battery and alternator. The headlight intensity
does not change with engine speed, so i don't think the batt is dead, and the alt. seems to be working fine.
What i do know is that my headlights are aimed too high, and will be making the adjustments tomorrow evening. What i'd like to know is if headlight bulbs lose their intensity over time? What are the possible causes, assuming that changing the bulbs doesn't help. Thanks.
