Lights flicker on '02

I have had my car in the shop a couple of times for this and they haven't got a clue.
As I'm driving at night the headlights flicker. It's really a brief shutdown, just a second, and then you wonder if you really saw them go off or not.
I'm just waiting for them to go off and stay off some night.

It doesn't come from lights reflecting in the dimmer sensor on the dash-checked that already. The alternator doesn't seem to have any problems.
I'm not sure, but I think it is connected (at times) with braking. My dealership tried to tell me the front end was dipping when I was braking-gee thanks for the advice. But that didn't explain why it does it when I'm not braking.
Anyone else have this problem?

I haven't had this problem on my Lesabre (yet), but I have had it on a couple of other vehicles. I would be crusing down the highway and the head lights would go off. In one, an old Ford truck, it was a loose connection in the brights switch. Sometimes, when I turned on the brights, it turned off the lights. In the jeep, the entire fuse box would wiggle loose on the firewall, under the hood. I cleaned off the connections well, but it still does it now and then. I just don't drive it after dark very often. If I do, I take a flash light. If both head lights are going out, I would look for something like a loose or corroded wiring harness connector. Also, pull and replace the fuse for the lights. Those would be the easy checks. If you can check it at night (lights on in the driveway) with a flash light, try to find the wiring and wobble things around to see if you can get it to do it. This is how if figued out the problem. Bumps in the road would shake it loose now and then. Good luck with it.

Take a look at my reply to the 92 LeSabre dying.

I'm assuming you have the auto headlights. Does your problem happen all the time or once in a great while? If it happens all the time or you know a time period that it should act up try not using the auto headlights override the headlights using the headlight switch. This may help narrow down your problem and make it easier to find.

Also when you say one second do you mean you see a flicker for a second or is it quicker than that?
