S-500 2000....my Xenon light on the drivers side is beginning to flicker on and off? Anyone has any ideas why that is happening??
When the lights warm up...about 30 min...while driving ...light begins to shut off...and flickers back on within seconds ....no bumps affect it....straight road.
Now this has happened to me about 1 year ago....twice...but now it happens every night...any ideas?????

 

most likely 1 of 2 issues.. Its either the bulb or possibly the ballast for the headlamp.. Try swapping the headlamp bulbs and see if the issue moves to the other side.. If not, I would suspect the ballast in the headlamp with the issue.. Just make sure not to touch the actual bulb when removing or installing them of course..

 

Im getting the same problem, if anyone has more info please post. Left headlight only. My friend swapped beams and didnt help. Probably a bad ballast?
