The adjustment screw does nothing on either headlight. The headlights light only about 25 feet ahead with the left headlight lighting the stripes in the road. I am forced to use the high beams until I can fix this.

Does anyone have a pic or schematic of how the adjuster on the back of the light assembly is supposed to work? There must be something missing.

I have attached a pic of my adjuster from the back of the assembly.
