ABSTRACT:
A neon-type pedestrian traffic signal which includes a housing. A partition divides the housing into two separate compartments, each compartment having a parabolic-shaped rear wall covered with a suitable reflective substance. A tubular-type neon lamp is mounted in each compartment as the focal point of the corresponding parabolic-shaped rear wall. Each neon lamp extends outwardly from the rear wall. The housing has an open front, and a face plate fits over the open front. The face plate has the appropriate "WALK" and "DONT WALK" symbols positioned over the respective compartments. An egg crate visor is mounted over the face plate to shield the pedestrian traffic signal from sunlight. Due to the configuration of the rear reflective wall of each compartment, the tendency for symbols on the face plate to be visible when not illuminated is minimized.
