    You have to realize that you've installed HIDs into a halogen housing setup. So the cut offs will be different. Also, with left hand drive cars the passenger headlight has a higher cut off due to the light shining onto the signs that are on the right side of the road.

    My only advice is to adjust the level. There are adjustment points under the hood and in circular holes that are built into the radiator frame. You will be able to see bolts surrounded by white cones. Adjust them when you are parked in front of a blank wall.

    The reason you have 2 cut-offs is because the 03 projector is different than 04-07. I replaced my RF housing with one from a 04 instantly noticed the difference, so I took the housings apart and took the projector from my 03 and retrofitted it. The cut-off plate in the 03 has 2 openings machined in while 04-07 has 1. I like it because when you get that @$$hole that won't pass the car in the slow lane at night you ride his @$$ and the upper cut-off shines right into his rear view mirror(they always move over after). I've also taken apart factory Xenon housings and the projector looks identical, so I really don't know if they are different. I've also been told the CTS's factory projectors are made out of crystal instead of glass like aftermarket and cheaper ones. I'm guessing that's why GM wants $680 for an assembly.

    You have to separate the headlight assembly, take the projector out, and the split the projector without chipping or cracking the lenses. I like the "sign spotters" personally.
