so earlier tonight both of my headlights went out, both low and high beams. they briefly came back on for a few mins only to go out again. all other lights are working just fine: both of the small front lights, front turning lights, and all rear lights. due to the holiday weekend i wont have a chance for the local shop to take a look at it (not taking it to the dealership scammers). any suggestions where i should start looking? i will check the fuses first thing tomorrow morning, though not holding my breath since the lights came back on momentarily. cant image how thats possible if the fuses blew out. next would be the relays, which makes me ask how do i tell if one is faulty? its easy when it comes to fuses, but is there some sort of device that "tests" relays? any other suggestions? thanks!
