On a mates van we made a small frame of quad which surrounded the housing and stopped it getting hit, I have seen them recessed where they cut out a hole and put a backing block of timber behind and then refitted the switch, the switch panel was then out of the way of errant feet or brooms, have also spotted one where the owner replaced the light with a small led light and the switch with a rocker switch which had a shield fitted like an aircraft armament switch cover, flip the cover then the toggle switch, looked very flash.
