It's really not that hard to do. I was given new silver stars for Christmas and finally last week installed them. The whole job (6 bulbs) only took about 1/2 hour. If it's on the drivers side it's easier than the passenger side due to access to the bulbs. Here is what I did for headlight replacement.
1) remove rubber cover on back of headlight unit.
2) remove wire connector, push side to side while pulling toward you.
3) release bulb clip. If you look in the hole you will see a clip that needs to be pushed forward then to the side to release it. The release is either on the top or bottom depending on if it's high or low beam. swing out of the way.
4)remove bulb. Make sure to look at the position of the tab on the bulb when removing. It will be either up or down depending on if it's high or low beam. If you don't follow this step the aim of the new bulb will be off. (this is were others have had problems).
5)install new bulb in reverse order. Do not touch glass area of bulb and make sure the tab is in the correct position and it seats properly in the socket.

Note: If your bulb replacement is on the passenger side and is the inner (high beam) it is very easy to access if you remove the coolant tank first. To remove the coolant tank.
1) remove electrical connector on the bottom of the tank.
2) remove the 2 nuts securing the tank on the top.
3) Pull tank straight up to release from the bottom mount. This is the hard part. The unit is mounted on the bottom in a rubber grommet, it is very tight and hard to release but should come loose.

good luck!
