Hummer H3 Tutorial easy way to remove the fog lights and install new step by step 

Hummer H3
"Use a panel remover to push a corner, allowing access to the fog lights and removing the screw from the back. This screw will be reused to adjust the light angle. No need to remove any back panel, just push it out to replace the old and install the new lights. Once the light is in place, secure it with the screw and push it into the groove."
