Help prevent collisions between forklifts and pedestrians by utilizing interactive LED signs. Motion sensors detect when a pedestrian is approaching a low visibility intersection and wirelessly activate the LED lights on the sign, warning forklift drivers that there is a pedestrian present. The double-sided sign is ideal for situations where forklift traffic comes at a blind intersection from two directions. The lights can be programmed to flash or be continuously lit, and the duration of time the sign is illuminated can also be adjusted to best fit the application.
