if your buying autozone "cool blue" bulbs or the phillips from there? I work at autozone, they don't stay blue at all they also don't look very blue. i think the're $20 per bulb?

If your look for a blue, get the nokya arctic white, they are white w/ a blue tint, they look pretty cool. Although they aren't as bright as oppose to getting "hyper white or super white" type bulbs.

here $22.
