I am replacing my current sealed beam headlights but I don't have a nice flat surface with a wall at one end.
The high beam of one lamp is burned out. So I am thinking of the following.
Place a panel about 5' to 6' in front of the car (far enough out?) Mark the position of the focal point of the good light. Measure the distance between the lamps and mark the panel that distance across from the focal point. Remove the old lamps. Install the new lamps and align to the two focus points.
Comments please.
TIA
