I have a need to adjust the aiming of the headlight on my 04 coupe. The outboard head light on the right side is way too low. The other three lights are perfect. Are these four lights all individually adjustable? Are they only adjustable as a unit? Maybe the bulb is bent or not seated in its position. The assembly appears not to be damaged. If I remove the unit the answer to my questions will be apparent. But then again, maybe removal of the unit is unnessary. Thought I would ask the forum before starting. I have have had good expearence with advise from you fellows.
