Probably needs a new light switch. If you jiggle the switch do they flicker?
Metal Halide can flicker when warming up cause it is starting to get hot inside. Or Metal Halide can flicker when it is about to burn out. Sometimes they even cycle.
replace your head light switch
no
Yes a bad circuit breaker and a bad light switch can cause a light to flicker when its turned on. It could also be caused by loose wiring going or coming from that paticular circuit. it also could be something in the fixture itself causing. Checking for loose connections is your cheapest and first route to go.
More that likely the headlight switch is bad. Turn your headlights on and when they start to flicker tap on the headlight switch real fast. If they flicker to you tapping on the switch, that's the problem. They had problems with that switch around that year. It's a pretty cheap fix and you can do it your self quickly. Can also be a sign of a failing alternator.

Sometimes when cornering, the overhead lights will flicker on in that model car. This is due to a flaw in the switch mechanism design, which holds the relay connection slightly apart from the bulb (when they touch the light is energized and turns on). When the car turns the centrifugal force will bring these two points together and the light turns on. To fix this, remove the plastic dome and switch cover and look for a tightening screw. If there is not a screw, you may be out of luck. If there is, tightening it should prevent this random flicker.
