Work carefully, go slow, and be patient. It can be done! The most common thing you have to worry about is getting the lamp seated all the way. There's kind of a "false seat", too. It will feal like the lamp is all the way in and the spring clip will even close, but when you turn on the lights they will only illuminate about 2 feet in front of you!

Do the driver's side first because the passenger side doesn't have a lot of room.

If you really get stuck you can pull the entire headlight assembly out, but that involves removing the front tires to get at the bolts underneath.
