Well I got mine installed, 6000k in stock headlight. No flashes back yet but I would like to readjust them before a cop makes me... kidding. I went out tonight, hunting for flat land with a wall. Drove the V close to the garage door (someones driveway . put down some tape at where I thought was the center of the beams. Backed off 25 feet and aimed a little lower then where the tape was. Then I had my little bro stay in the road and I passed by. He said light didnt blind him. Is this technique ok for HIDs in stock headlight or should I measure distance between the one headlight to the other, ground to headlight?
