How do you replace the head lights of a 2002 Jeep Cherokee Laredo?

There is no such thing as a 2002 Jeep Cherokee. The last year was 2001.

There is a Torx (Star) bolt on top of the headlight pretty much in the middle of the light. There's only one for each headlight. Remove that bolt, then pull the lights forward. It takes some effort, but they're only held in with clips and they'll pop out. It might help to start by prying at the bottom of the light. Hope this helps.
