I don't know if this applies to smaller lifts like we have but I'm pretty sure that the huge 12" ford lifts require the headlights to be adjusted downward to properly illuminate the road. well either way, one of my headlights went out of whack and its driving me nuts, the problem is i don't know which one. firstly, is there a technique or guidelines i can follow for getting the correct angle to best benefit myself and other drivers? secondly, how do i get the lamp to stay in the new location? i was jiggling it last night and it was moving fairly easily, but both just went right back to the position they were in. thanks guys
