1)personally, I like them very much. With a projector type headlight, you can have a much brighter light (HID) because the light is focused were you need it and out of the eyes of oncoming traffic.
2) Yes, you have a very wide range of adjustment: Best guess
Horizontal: R 30degree & L 30 degree
Vertical: U 20degree & D 20degree
The best result I got were from setting out a marker dead center of the truck at 30'. I overlapped the beams centered on marker and raised horizontal line to about 4-5' off the ground. I'll take some pictures later
If you don't alighn your lights correctly, you could suffer from dead spots in your line of sight. This will piss you off, turst me.
I also went with the yellow hallogen fog lights:
My understanding is that it is important for fog lights to be one color (rather than white, which is all colors) because the different wavelengths(colors) of visible light scatter off the fog droplets differently. This phenomenon is known as "dispersion," because the different colors of light in an image will separate from each other,causing the image to "disperse." If you illuminate the road with only one wavelength (color) of light, the images of the objects you see will still become somewhat blurry because of the scattering of light by the fog, but at least you won't have extra problems from dispersion. So, if we want to use just one wavelength of light, which wavelength should we use? It turns out that light with short wavelengths scatters more than light with long wavelengths (short to long: violet, indigo, blue, green, yellow, orange, red). So, a long wavelength light will be best. There's another thing to consider, too: our eyes are not equally sensitive to all colors. It turns out that we are most sensitive to yellow and green light. So, our best compromise between sensitivity for our eyes and a long wavelength for least scattering is yellow light. R.B Jr., Ph.D.
There is alot of debate on the subject but this is just my opinion...
