Well my girlfriend has a 2005 Chevy Cobalt and is in love with purple headlight bulbs (12000k correct?) since she saw them on a car the other day. My question is can anyone recommend a good set of these bulbs? I have seen a few sets that are really bright around town. The thing is that I want to find a set that has good light output since I want her to be safe would prefer it to be at least stock output. Can anyone help me out here? I have considered HID's but they are not made for halogen housings which means the throw sucks and blinds other people plus I don't want to rewire her headlights and if I did I would go to the junkyard and clip the harnesses off a wreck since I really don't want to mess with her stockers.
