Dear all, I took delivery of my 2003 CLK 320 which was equipped with xenon headlights. On the first day the computer displayed right headlight malfunction. I returned it to the dealer who replaced the entire right headlight assembly. Now I notice a purple rim of light at the top on the beam eg, when my lights shine on a car in front of me. Is this normal? I have not noticed it on other Xenon lights...the dealer hasn't been able to tell me if this is normal or not???!!!
