Aiming headlites

There should be a phillips head screw in the center line of the light outside the circumfrence(sp) if its at the bottom of the light screw in (clockwise) to aim down. Ccw if the adjustment screw is at the top of the light. A back yard aim is, park six feet away from a wall messure center line hieght of the lights. Subtract one inch. Mark that line on wall turn on lihgts and adjust center of beam to that line hieght. And about one inch outward side to side. Good luck

It could have a hex shaft that sticks up behind the headlight. Takes an oddball socket like a 5mm hex or something like that.
