Same reason they do in mine -- its a crappy design -- Have you ever taken a light bulb and shook it? If you do it enough you will break the filament --- the lights on the Firebird Slam down with some pretty good force -- I tend to replace them about every 3 month because of that, sometimes you will find the socket came off as well
you need to replace the fuse for the headlights.
Bad voltage regulator
It might be because of moisture. Mine would go out every time it rained. I had my mechanic put a new silicon seal on the headlights and that solved it for me.
There is a voltage regulator located on the internals of you alternator replace the altenator. Voltage regulator keeps voltage constant and stops spikes in power output, this is what is causing your headlights to blow.
Defective PW motor, short in the wiring or the switch.
Short in the wiring or the lamp holder for the tail light is corroded.
When it is raining during the day you should always keep your headlights on.
Find out why the fuse is blowing. You have a short or the circuit is overloaded.
Just pull the parking brake up one click. It won't engage the brake, but it bypasses the headlights.
Voltage too high - bad voltage regulator on alternator. I bet your dash lights are very bright also.... Change out that alternator before you start popping other bulbs....
yes
The alternator is on it's way out.
