Hello, I am sure this topic has been brought up many times. I am sorry if you have heard this problem before.
I purchased a pair of Xenon headlights to replace the standard halogen pair that came out on my 2000 S Type. The problem is the do not always come on when you first try them. You can turn the switch on and then off untill they both fire up. Once the lights have been on for awhile they work without fail ever time. Could it be balast or iginitors? or wired wrong?
