Easy to Install:
1. Take the screws out and gently remove the old light. Clean the gasket area.(Alcohol could help clean the area better.)
2. Plug in and make sure to tuck the whole hardware in.
3. Screw it back in the place. Please don't tighten it down all the way yet in the beginning, or the case would be cracked. Put the two screws in and then tighten it down.
Note: A flathead screwdriver will be needed for the installation.
