It could be because its running out of battery
Battery is dead?
If your interior lights are dimming, either your battery or starter could be failing. You should have your car checked.
you drain your battery when you leave your lights on
out of gas prbably
The best way to find out if your headlights are dimming is to turn your lights on when it's dark at your house and check and see. Also you can go to auto zone and ask if the lights in your car are dimming and what you can do to fix them.
there is a short in the relay for the head lights
Car battery is run down.
when i play music in my car the lights dimm i wanted to know if a capacitor would stop that problem
yes but wont run for long, you will have no lights, horn, radio ect.
Yes, yes it does. Try thinking like this: If you play at really low volume in your car, and your amp is rated at 2000w, powered with a bad battery, then you won't notice any dimming in the lights, but when you crank it up. Then you get dimming lights.
Take it out of reverse.
The capacitor will not cause dimming, whatever it is that the capacitor is being used for (usually helping drive a bass amp) is what causes the dimming. A capacitor is a quick charge and quick discharge battery basically, so when the amp has depleted the power in the cap it still must go to the car battery for power and that is when there will be dimming lights.
