A housing for protecting a garage door safety beam emitter or receiver from impact and from the elements. The housing has a transverse plane of symmetry such that the same style housing may be used over the emitter and over the receiver, the housings being minor images of each other when installed. The housing includes a flange by which the housing may be attached to a garage door track or to the framework around the garage door. The housing preferably is formed of plastic such that it can be trimmed to accommodate installation, for example, around a foundation and includes a side wall with an aperture through which LED diagnostic lights associated with the emitter or receiver may be viewed.
