To many lights are burning out on my car. But it's never the same one, they diddn't all burn out at the same time. One foglight, tail, daytime headlight, brake, 2 interior little buttoms, and on my speedometer it's kinda dull in one place....
I think it might have something to do with my sound system. I'm running 2 amps, a 4 channel that runs my interior speakers, and a mono which runs only one 12".
I recently just installed a capacitor, but i dont know how well this worked since I just discovered today that my brake light ws out.
I dont know if the lights are just old, or if theres something else wrong.
What can I do to fix this?
Thanks

 

Maybe your alternator is messing up?

 

Yeah, possible power surges due to a bad voltage regulator (built into alternator). Take car to AutoZone for free testing of the charging system.

 

Measure the voltage at the battery with the engine running but everything else turned off. It should not be more than about 14.5 volts. Over 15.5 is definitely a problem.

 

Ok, I will test it tomorrow. If it is over what do I do?

 

Excessive voltage means you will probably need to replace the alternator, or take the alternator apart and replace the regulator unit in it.

I was also thinking that vibration (e.g. subwoofer) tends to be murder on bulbs.

 

Well before I got my Cap, every time the bass hit the lights would flicker alittle bit. But now that the cap is in it's fine....

 

I tested it, and it's at 14.4
