My main compliant is that I can't seem to get a definitive answer as to whether the square screw (?) with the threads is a adjustment screw, or not. I get these comments that state "turn the screw clockwise to raise, counterclockwise to lower. Which one, theres so much plastic that I"m afraid that if I turn something that should not be turned, I'll break something. Additionally, what are the vertical screws suppose to do. I've rotated them, and they just rotate, nothing happens? This is my second set, the first one was clear, decided to go smoked. First set didn't require adjusting. I've seen on numerous forums that many complain that there are no instructions about adjusting. I will ditto those comments. By the way, I'm 77 years old, grew up in California
when customs and hot rods were king. Had several customs, and this is the first time I've had issues with lights.
