ABSTRACT:
An adapter unit is provided which may be easily and quickly fitted into existing pedestrian traffic control signals to adapt such signals to an assembly in which luminous gaseous tube signal elements are mounted in an enclosed capsule, or module, which, in turn, is supported within the original housing of the signal. The adapter unit of the invention comprises a signal illuminating capsule which has a tray-like configuration, and which is mounted in the cover of the traffic control signal by means of a pair of cross bars which are releasably clipped into brackets fixed to the upper and lower rear edges of the cover.
