The Lighted X Runway Closure Marker is a lighted visual aid for indicating to airplane pilots that an airport runway is closed. Designed and certified in accordance with FAA requirements, its flashing lights can be seen both day and night from miles away, clearly discernible as a giant “X” and distinguishable from other lighted visual devices used at airports, signifying that the runway is not open for landings. The Lighted X trailer is easy to transport, and can be deployed by one person in less than five minutes.

The “X” shape comprises nine lights on four independent arms and a mast. When deployed, the mast tilts upward to nearly vertical, and the “X” is centered at the top of the mast. For transport and storage, the mast tilts downward and the arms pivot together. The entire assembly lies flat when stowed, held in place by support brackets and lock-pins.

Each arm includes two high-efficiency LED light fixtures, with one additional light fixture located at the center of the “X.” LEDs provide highly directional light distribution, resulting in high luminosity and low power consumption.

System power is provided by batteries, which are charged continuously by a diesel engine. The system can run continuously for more than a week without intervention or refueling, and the batteries continue to power the lights if the engine shuts down.

A weather-resistant enclosure houses the power system and has two side doors for easy access. A hinged top panel provides greater access when maintenance is required. The side doors may be opened while the maintenance panel is raised. An optional secondary-containment system protects against fluid leaks, spills, and drips.

FEATURES & BENEFITS

Transport

  • Compact trailer is easy to maneuver

  • Cradles with locking pins hold display arms in place during transport

Setup

  • Heavy-duty hand-winch allows one person to easily raise and lower “X” assembly
  • Lock-pins hold the assembly in place during operation
  • Full deployment by one person takes less than five minutes

Operation

  • Fully enclosed steel equipment-bay protects controls, engine, and other components from the elements
  • Two gull-wing doors with handles and latches provide access to controls, fuel tank, engine, and electronics
  • Locking door handles protect equipment bay from unauthorized access
  • Control panel features elapsed hour meter, engine indicator lights, and brightness-selection switch
