PedSafety TLPI is an innovative pedestrian safety solution that enhances the visibility of pedestrian signals, especially for drivers turning right. It features a highly visible LED sign that displays "Walk" or "Don't Walk" signals, synchronized with the pedestrian signal head. The TLPI utilizes existing field wires and is not polarity dependent, making installation simple and efficient. It can be powered by a 120V power supply or solar panels, providing versatility in different environments. The TLPI is designed to improve pedestrian safety and reduce the risk of accidents at intersections.
