I'd like to know measurements for aiming my truck's headlights. Park how far from the garage wall? Height and lateral measurements for right and left headlights? Thanks for any light you can shed on this...
Wow! Way too technical for me! I park on a level stretch of parking lot, or road. Tape a piece of cardboard over one light, adjust it till I like it. Move the cardboard to the other side, and repeat the process.
