I hate to say it but something isn't right with that car. I fear it was probably involved in a minor front end "incident"... have a body guy look over the car. There's no reason one light is out of aim. I don't think GTs have a manual adjustment (I could be wrong on that).
that makes sense. There is no perfect fixture and it would need alignment. I spoke too soon as this is my first set of manual leveling HIDs and I've not looked at the housing. Come to think manual leveling is limited to vert axis and both servos move at the same rateThe lights have to be adjustable, it is FMVSS regulation that they be aim-able (the in cabin leveler doesn't count as aiming).
I have never heard of this. How does age/mileage cause a mechanical housings, which does not endure any physical forces or stress expect aero, go out of alignment (unless there is a product issue)? I'd like to know more if anyone can share details.Headlights can go out of alignment over time and as mileage increases.

Misaligned car headlights are not only a potential hazard for you, but for other drivers as well. Changes in ride height, vehicle load and tire size, or minor fender benders and everyday use can all cause your car headlights to lose their aim. Aiming automotive headlights is an easy task and is best performed when replacing headlight bulbs or lamps.
There are several reasons that headlights lose their proper aim; one of the most common culprits is a collision that involves front-end damage, but the can also just lose their aim over time for other reasons (like repeatedly opening and closing the hood over time).
Unfortunately the links don't show up on my phone but the only remotely possible event is opening/closing your hood - really?? I don't buy that unless the car's front cross beam was designed where the light housing takes the blunt of the load, which I don't think anyone does.

In addition to collision, headlight replacement, suspension changes, and uneven tire pressure... breakage or failure of headlamp mount/aim components can contribute misalignment of beam pattern. Also road vibration, given enough time, will tend to shake-rattle-and-roll the aim out of spec. And remember, they're not necessarily aimed correctly when new!
