30k is deep purple..and as for blinding people..you have to understand..those HIDs only blind people if you don't aim them. it's inevitable when you're going downhill and someone is coming up hill towards your car..but in all other situations HIDs don't blind people if you aim them. i aimed mine and they are great. as for why i don't like the purple..because i got pulled over with them, i mean..i'm going to keep them in, but i will probably switch back to 6k after a little and just keep switching back and forth when i get tired of the color.
