Hi everybody
Would be happy to get some advice on the xenon lights. I recently got myself a 2003 xj8 x350 .The right xenon bulb was flickering so I exchanged them both sides as well as all the other bulbs in the front , changed the batterie and cleaned tne mass connection on the right.FLICKERING DISAPPEARED. Then I drove home in the dark and I found the result hm not yet dangerous but back in 1985. Lousy ...
Since the car is almost 18 years old I thought cleaning the inside glasses might be an idea for the start . But could the regulating module cause this ?

 

I've moved your question from General Tech Help to X350 forum. This is the place to post technical questions about your model.
