Lamp Assembly Installation
Suzo-Happ has developed the exclusive "Posi-Lok" design to assure a positive fit between the button bezel and the lampholder assembly.  Simply insert the lampholder assembly into the button bezel (step 1), make sure that the notch on the lampholder assembly is aligned with the tab on the bezel assembly (step 2), then twist or turn the lampholder assembly until it locks in place (step 3).
