those are the old version gen 1 i believe (maybe 2). the newest is gen 3 and gives you the best projector and more of a stock look.
also they use 9006 bulb so you don't have to cut your stock harness like the old ones. so if your HID bulb or blaster goes out can pop in the stock bulb and will be good.
they come in chrome or black
they looks like this and can tell them apart since they have 3 white leds were the amber reflector is on the sides
