I don't know if you can tell, but they're aimed a couple of degrees UP. They're what I call ''hill approach'' lights. If you're coming up to or heading down a steep hill at night, the up-aimed lights give you a ''landing zone'' ahead. Headlights or driving lights aimed normally just blast a bright spot into the ground directly ahead, and you can't see what's on the ground you're about to drive onto. The steeper the hill, the worst the blind area.

With the HID's on the bumper, I can see 3,000 feet of dirt ahead, so the overheads do little more than show up flying moths anyway. And... HID's mounted above the windshield (light-bar, roof-rack) don't work, you can't see past the beam glare. (maybe within ten minutes of a heavy rain in perfectly clean air)
