The pedestrian signal head uses ultra-bright LED technology to project highly visible signs, contributing to pedestrian safety. Having each LED symbol (a pedestrian or a hand) superimposed in a single section of the 12-inch (305 mm) pedestrian signal head allows the signal to perform functions that would otherwise require two sections or a larger housing. Each LED symbol lights up when a 120 VAC power is applied to the appropriate circuit using the intersection controller. |
