    Abstract: A removable cover for a photocell housing having a photocell sensor for detecting light to activate lights or other electrical devices is disclosed. The cover is made of an opaque and resiliently flexible elastomeric material having an end wall and a skirt extending therefrom. An opening is formed at a distal edge of the skirt, such that the end wall and skirt define an internal cavity configured to removably receive the photocell housing therein. The cover conforms to the photocell housing to create a frictional-fit therewith so as to obstruct light from entering the photocell sensor to allow repair and maintenance of the lights or electrical devices controlled by the photocell sensor.
