Have a weird problem..

[Got Gear?]

Hey guys,

You may remember my post about me being an idiot cause I spent a whole bunch of time trying to figure out why my lights wouldn't work....and the problem turned out to be a couple of burnt out lightbulbs.

I replaced the bulbs on Tuesday and they're burnt out already!

After some fooling around, I think I've found the culprit!! The two 12" subs, a 15" sub, and the 1000W stereo system! Turns out that the stereo system shakes these bulbs so hard that they burn out when you put your foot on the brake and the bass hits. (combintion of vibration and the red-hot filament).

I've already looked into those LED lights, but they only seem to make these for newer cars and ricers.. nothing for a 1970 mustang.

Any ideas? And NO! I'm not turning the stereo down

Turn the stereo down

No matter what those lights shouldn't be going out that easily! I'd contact the manufacturer & complain!
Do you have your current system running off the primary battery?

dynomatt the trunk.

Run your system off an additional battery

That won't stop the vibrations......

It's all on 1 battery.. Optima Yellow Top.

I'm curious as to why you think I need another battery. Low voltage won't burn out a light... and I doubt that I'm getting any voltage spikes (past 15V anyway). I have a voltmeter mounted in the car.. and yes the voltage will drop as low as 10.5V during a good long bass beat.. but it never seems to go above 14.4V.

I also have a 1 Farad Stiffening cap in there to help smooth out voltages..

Why don't you try to pad the bulbs somehow so the vibrations are limited? Maybe with some electrical tape or something?

It's done already..A little.

Dynamat works best for getting out the rattles.. it does this by aborbing higher frequency sounds...not by stopping the vibrations.

You can litterally see the metal taillight panals move about 1cm back and forth..at like 30-80 times a second..

Well the problem is that the tailights are mounted inside a metal housing.. this housing is mounted to the metal trunk pannel. This whole pannel flexes approx 1cm when the bass hits.. which means the taillight housing along with the bulbs also get shaken. It's not the bulbs vibrating in the housing's, it's the whole housing rattleing..

try insulating the bulb socket with dumdum

What's this dumdum stuff? Never heard of it...
