>get a nice set of lights for my car ...
You haven't said why you want replacement lights although there's only 2 valid reasons;
2. Brighter illumination
If it's 1, there's a lot of blue tinted lamps out there and it's just a matter of deciding which shade of blue you prefer. Here in Ontario, I know of several people that have been stopped by a police officer and been given 24 hrs to lose the bluish lights. (emergency vehicles only)
If 2, as has been said many times, adding a blue (or any color) tint to a lamp blocks the other spectral colors and diminishes actual light output. And since the coating absorbs some of the light energy, it runs much hotter than a clear one, resulting in greatly shortened lamp life.
The obvious exception, of course, is the xenon HID, which makes the bluish light naturally. There are MANY lamps out there that use either xenon or HID in their name. If it has a filament, it ain't one. If it doesn't use a ballast, it ain't one.
