11. Next, I plugged in the bulb and installed the bezel. To help keep the assembly nice and sanitary Robbie and Todd designed the bezel to be a screw/press fit, where you use the two rubber gaskets to sandwich the outer edge of the bulb. As you screw the bezel on it compresses the gaskets. Once fully tightened the pressure and rubber surface of the outer gasket pushing against the inside of the bezel locks it in place like a retainer or tensioner. No need for set or lock screws. One tip before twisting the bezel on is to lube the outer surface of the gasket that faces the inside of the bezel. This will allow the bezel to slide against the gasket without the gasket getting bunched up. When the lube dries the bezel will essentially be locked in place. To unscrew, you simply apply some pressure to the center of the bulb and loosen the bezel.
