Well, you can get at it from the back while laying on the ground. It helps if you have two wrists.

The way I changed mine was I took out the head light assembly (there are two plastic tabs that you can reach from the top (at least that is the way mine is)). The bulb may be different than mine but once you take out the headlight, just don't replace it till you get the replacement. I got mine at Autozone. This will not affect you headlight aim. Good luck, it isn't that hard.
