LED preemptive train crossing signs, installed at railroad and pedestrian crossings, alert the public to approaching train traffic. Secondary warning LED train crossing signs at transit stations and railroad crossings have been shown to enhance public safety.
Signal-Tech's dynamic message signs are designed to illuminate a message or symbol when activated and blank out the message or make the message extinguish when deactivated. These LED blank out signs can also be designed to flash and emit an audio alarm when the message is activated. Signs available in 12VDC, 24VDC, and 120V.
