Flickering headlights

Does anyone know what causes the head lites to flicker? Also dash lites and interior lites

If you have a system with a big amp drainning power. (Disco lights) that is the prob. Or if you don't I would say your alternator is not charging your battery.

there is apost about this already, you can do a search on it, I dont remember what it ended up being, but I think it was the DRL sensor. but just do a search and you should find it.

The BCM had to be repalced. You can do it yourself but then the car won't start after the new one is installed. It will need to be programed. I've been told the BCM is not expensive but it needs programmed afterwards.

Well i noticed the other day...when i switched my high beams on, then switched them back off, the drivers side headlight wouldn't come on for about five seconds...I did if a few times with the same results....I'm pretty sure it's not the bulb going bad. I tried hitting it a few times when it was parked trying to get it to flicker again with no results.....any ideas
