    Well, what I know is this:  not all of these types are available for all cars.  If you want projector headlamps, you'll have to buy a car with projector headlamps, which are usually HID lamps as well.  There is very little that can be done to upgrade these.  Xenon lamps are halogen lamps that give off a bluer or whiter light than normal halogen bulbs.  This light is closer to the color of sunlight, and easier for the eye to see.  This makes the xenon lamp seem brighter to the eye.  Angel eyes are a ring of smaller lights around the existing lamp, usually in a color such as blue or purple.  State laws regulate what colors can be displayed on the front of a car, and you need to check it out before you do something like that.  Personally, I have no use for them.  Some halogen-equipped cars can be converted to HID with special bulb kits.  This is, for my money, the best thing to do.  It gives you brighter light so you can see better, and it reduces the current draw of the lights by more than half.  The prices of these kits vary wildly, so do a little shopping before you buy.  If replacing a H4 bulb, or a 9004, make sure that you get a HID replacement that supports both the high and low beams separately; some don't.
