I actually have the Morimoto projectors and HID's in my 08 Aveo. They are ok. They are entry level but better than stock halogen headlights. You don't want to go higher than 5000k. Anything higher than that and you will start losing brightness. 4300k is the optimal color. Just PLEASE don't do plug and play. I hate it when people just throw bulbs in their stock headlights. Output is crappy and you blind everyone in front of you. If you can't afford projectors then just stay stock.
