replace your head light switch
a flat battery
I have an 2005 and the headlights on it will dim, and then brighten back to normal. I bought it brand new, and it has done it since I bought it. I actually took it back to the dealership, and asked them about it, and they said that Chevy knew that it would do that, but that the car would keep running, and that there was nothing that they could do about it. Hope this helps.
Alternator is failing.
LCD's are made up of lines that project an image on the screen. These lines constantly move, sometimes up and down, and sometimes side to side...this causes a flicker often seen on older LCD monitor's.
it is caused by the alternator voltage regulator switching on and off to charge the battery, this problem is encountered on many makes of car, you may not of noticed it before prior to exchanging the battery.
The primary causes for the lights to flicker inside on a 2002 Chrysler Sebring LXI is a loose bulb or wire. This can occur when the vehicle has experienced rough road conditions and excessive vibration.
On my 89 Probe it overcharged because I needed a new alternator. Sometimes a bad computer causes "spikes" in the voltage. In this case, turn the headlights on at night, if they flicker like high beams, then the computer is NG. -CE
There are a few things that can cause your computer screen to flicker. One being other electronic devices being placed into close proximity of the computer. Also, the rate at which your computer refreshes can also cause the screen to flicker.
I think it is a dying battery
