Replacing incandescent bulbs with DDP® LED lamps in railway signal applications such as barrier lighting, speed signaling, weak route signaling and position light signals, saves cost and improves safety.
The advantages that solid-state LEDs offer are particularly suitable for the railway signaling where lamps are continuously exposed to harsh conditions. Burned-out incandescent bulbs require costly maintenance and may create safety concerns. Replacing incandescent bulbs with DDP® LED lamps in railway signal applications such as barrier lighting, speed signaling, weak route signaling and position light signals, will provide up to ten years of maintenance-free operation. Since 1970, DDP Engineered LED Solutions has pioneered the design and manufacturing of LED technology to replace incandescent bulbs in harsh environments. We design our LED lamps to provide direct replacement of common lamps used in existing railway signal equipment without modification to existing equipment.
