Hello, everyone.
Thank you for being interested in this topic.
I just wanted to ask you guys if there are two different relays for left / right headlights or there is only one for both. My Z4 has got SONER angel-eyes on it, but left discharged low-beam is not working since 2 weeks ago. I thought it was a bulb issue, so I replaced it and a ballast also, but it did not make any difference. To check the problem there, I tried to flash the hi-beam (unlike the factory lights, SONER has two different bulbs for hi; H1 and low; H7) and then I found out the hi-beam on the left hand side is not working as well.
Is there anybody who has been in the same situation before?
