US lamp regulations do not require cars to have their lamps aimed at any particular degree up or down depending on the height of the vehicle. Therefore my Matrix and your F-150 utilize the same plane for aiming the lamps whereas in European standards, a taller vehicle would be required to have proper aiming so the beam points slightly downward relative to the lamps distance from the ground.

It's the same reason a lot of the luxury cars with projector HIDs in the US have auto-level as an option or standard equip. It's standard to have in Europe. So adding an HID to something that is already taller than a standard car means a lot more scattered light gets tossed around to other people.

I could go on for paragraphs about lighting as I've spent a lot of time/money/effort in applications and research on the topic and my own trial/errors with cars.
My F150 has a 4" lift with 35 inch tires. No glare. No pissed off drivers. I've looked at them in a buddy's car when he's driving my truck and they aren't any worse than any other car on the road.
