they're not very bright in comparison to silverstars...
because of the amount of color, not much light actually gets on the road.... but they look decent when you're outside the car. cant even compare to the color of HID's though. I would recommend something more like MTEC bulbs if you want an aftermarket blue-ish hue bulb..... or Sylvania Silverstars if you're more interested in just lighting up the road more clearly.
the turn signal is a completely different bulb type than the headlight bulb. luminics does not make turn signal bulbs as far as i know.
