Runway Alignment Indicator Lights | LED RAIL
Compliance and Applications
• FAA AC 150/5340-30, 150/5345-51
• Canada: TP 312 5th Edition
Use of sequential flashing lights provide pilots a visual transition from instrument flight to visual flight during landing. The RAIL (Runway Alignment Indicator Lights) are used within an ALSF, MALSF, MALSR or SSALR approach system help the pilot align with the center of the approaching runway threshold.
Features
• Low maintenance costs
• Long-life LED for years of service
• Three intensities (low, medium, high)
• Field programmable sequence timing
• Flash monitoring
• Elapsed time meter
• Current or voltage driven
• L830-4 100W isolation transformers

We provide the L-849(L) Uni-directional system to operate within each Approach Lighting System as a RAIL (Runway Alignment Indicator Light). Each RAIL system will provide a sequence of flashing lights to create a clear visual guide to align with runway threshold.
