Signal-Tech’s LED Road signs are ideal for traffic and lane control on roadways, bridges, tunnels, and tollways. These signs feature a rugged NEMA 3RX/IP55 or NEMA 4X/IP66-rated cabinet construction with custom or MUTCD-compliant symbols laid out in LEDs. Messages can be static, always on, or blank out/extinguish when deactivated. LEDs are rated for 100,000 hours of continual life, making our signs virtually maintenance-free.
