My Vectra 98 has 2 bulbs dead in the front left Headlight. Both The Parking light bulb and the Dipped bulb beside it will not light. I have tested both bulbs with a multimeter and they are ok, but there appears to be to no voltage present in their sockets. First thing that came to my mind was a blown fuse but I have tested all the fuses and they are fine.
just wondering if there is any other obvious reason for this.........? suggestions welcome
