When starting the car at night, I have lights for a few minutes, then they cut out. I immediately hit the high beams, which works for a few minutes then they cut out. When I go back to the standard lights, they work - and the problem disappears until the next night. I have decided I can't drive at night till this is fixed. My mechanic does not know how to repair it but suspects that it is an electrical issue not related to bulb replacement ( they have been replaced). I dread going to a dealer because I have had exceptionally bad customer service at the ones in my area.
