I think that's why the state Patrol said "Properly adjusted Xenons.."pod13 said:
My xenons have a well defined line where the beam is hits the pavement in front of my car. With my last car the halogen lights used to light up the inside of the car in front of me when I pulled up behind at a traffic signal. With the xenons, the inside of the car in front of me is completely dark. The beam strikes BELOW the other guys rear window.
