Headlights are pulsing
Now that it's winter and I've started using my heater, I've noticed that my headlights have started pulsing. It occurs both when the car is moving and when its idling and seems most severe when I have the heater and stereo on. Any ideas as to what this might be?

You're battery is not being charged corectly. Get the alternator and the battery checked out.
If you don't get it checked out make sure you have a road survival kit in the trunk in case it dies on you.

Yep, I'm right there with you Sterling. I stopped by Shuck's immediately after posting and had my battery and alt. checked. During the test my alternator suged to 15.2V but, according to the Shuck's employee conducting the test, my alternator and battery were OK.

Gotcha, thanks for the help guys. Strangely my headlights have stopped pulsing and I'm thinking this is a good sign or a really bad sign. Either way, after the holidays I plan on buying a new alternator. I miss the days of DIY alternator repair tho.
