Keep in mind that while these bulbs give you the look, they come at a cost. For starters, expect the bulb to last about a year or so. I've had bulbs last 3 years but most of the time it's just 1. Also, some bulbs run hotter so be aware of melting plastics.

One last thing, don't expect to see better with these lights. They are not a true HID light so they don't have as much visible or usable light to offer. The spectrum is actually quite small here and you do not see better with these lights. I find them to be worst than standard but if you are going for the look, they do ok.
