My headlights have been on & off the car so many times it's not funny. I've forgotten what the low beam pattern is *supposed* to look like. Right now, the beams hit the ground maybe 40 feet in front of the car (I haven't measured) and don't come together. Should they meet on the ground when the car is level? The area covered extends to pretty much perpendicular to the sides of the car. Also, my left low beam pattern is "rounder" than the right side. Is there a reason for this?
