It may be the result of a malfunctioning alternator, or simply a loose alternator belt. When the car is idling, the rpm's of the engine are decreased. This means that the battery is putting out energy, but the engine is not moving the alternator fast enough to refill the charge. When the car is moving, the alternator is getting enough power to keep the lights from dimming.

Why does a 2004 Volvo S40 stall?
We had the same problem and we were told by the dealer that it was because the ambient temperature sensor was shorting out?!? Since we had that problem fixed we've also had the problem of our passenger-side headlight working intermittently and this morning both headlights wouldn't work.

What if your headlights on your 99 Jeep Grand Cherokee intermittently turn on and off while the Jeep is turned off and the lights are on the auto setting?
(http://www.wjjeeps.com/lamps/headlamps.htm) AUTO HEADLIGHTS CYCLE ON AND OFF WHEN THE VEHICLE IS PARKED AND TURNED OFF (with headlamp switch in "Auto" mode) The problem is most prominent on 1999-2001 WJ's, but it could apply to the 2002-2004 WJ's. The problem could be in the switch. The switch is a multiplexed circuit, the resistance of the HEADLIGHT ON position is very close to the AUTO position; the switch has been updated to correct this problem.

No. The brightness is determined by your monitor. While you can artificially increase the white balance with the better graphics cards, this will not solve the problem. You'll have to get a higher brightness monitor.
Why do your hi beam headlights go off while driving?
I had a problem with my headlights going off, not the high beams. Replaced the rectangular silver can thingy at the fuse panel under the dash on the drivers side. I put a higher rated one in, which is a no no, but it solved the problem of the headlights going out.
