Hello,
i have a problem with my Headlight !

High Beam is fully working with both filaments.

Low beam does not work and i do not know way!!!!
Perhaps the relay is broken ??
I dont know where it is and how to fix it.

Anybody know what to do ?!

It does not have a relay.

If your H4 bulbs is ok and the contacts are clean (check with a multimeter that you dont' have 12v) then your problem is either in the switch or the wiring.

The switch can be taken apart fairly easily to check the contacts.

Hope that is of some help

Problem is fixed !
One of the contacts was not inside anymore an that was the Problem.
