ok so ive read through all the headlight break-downs on here and none are similar to mine so heres the thing. i have a 72 510 (2dr) lights worked fine for the first 2 days i had it then the lows/highs went out. all my other lights come on (interior, corners, blinkers etc.) i checked the headlight fuses and both checked out good...switch is still clicking when i pull it in the (on) position so im sure its not the switch...
what else can i check?
