Be a little more specific and maybe someone can help.  Are your headlights dimming, or are they not working right?  Did you use a wiring harness for your vehicle to connect your new stereo?  If you did not, you may be using a wrong wire for power or ground (illumination or dimmer), which is causing you problems.  You need to rectify this before you cause any serious harm to your vehicle.

If your headlights are just dimming, consider upgrading to a relayed headlight harness to keep the voltage up higher.  A lot of times the factory wiring in cars will rob you of over 1 volt from the battery until it makes it to the headlights.
