Changing headlight bulbs is simple. You simply need to remove the rubber sleeve that sits over the back of the bulb, and unplug the bulb from the harness. You'll see the bulb is just held in by a metal pressure clip. Squeeze the correct point and you'll be able to swivel the clip back and remove the bulb. Installation is just the reverse.
Silverstars are just plug and play, you don't need to do anything special for them.
Dang, PCH there for the win with the link
