Our "Scare Light" is the Big Round one! The 4 screw hole areas that hold the Lens on were Filled with Caulk,what a job to dig it out!
Removed the 4 Philips screws and the Lens comes off,there is a Gasket that stays on the Base! the Base is Caulked to the Sidewall plus 4 screws! I placed "Close Cell Sponge" back in the Lens holes,1/2" Dia X 1/2 long!
Youroo!!
