Trini,
I have the 3200s and they are actual driving lights. I wouldn't exactly call them blue, but they are much brighter than my headlights. I know that the 2200s are strictly foglamps and not as bright, but I can't really say much about the color. If you want the brighter light, go with the 3200s. As for installation, I believe there are brackets for sale in the GP store for these. I just wish they would have had them when I put mine in. I hope I gave you some insight...
