Hello, everyone. I've got W203 C270 CDI, 2001y Mercedes Benz. I cannot pass technical inspection, because there some issues with my Bi-xenon headlights. I've bought new D2S bulbs, but not very expensive ones, at the technical inspection shows that there is almost no lights, they are dead... How can i solve this problem? On both headlights is the same problem... The main problem is Low beam light, high beam is alright.. I have noticed that headlights looks foggy, I am planning to polish them. It would help a bit or not?
I am attaching my headlights pic. Thank you for your time!

 

Your headlights look fine. If you have low light output it may be the cheap bulbs or the igniter/ballast

 

check the ground wire for the lights as that will cause an issue as well. Since it is both lights it will more than likely be something that is common rather than ignitor and ballasts since each light has it's own.

 

post a picture with the lights on!
