LED Runway Distance Remaining Sign
RDRS-H-L
An internally lit elevated sign showing white digits on black, set at intervals along the runway to tell a crew on the roll how much runway is left ahead. Internal reflective illumination lights the digits evenly and without shadows, so one glance at speed is enough; the front frame opens without tools and lifts clear of the box, keeping runway-side cleaning inside a short closure window. Posts running through the extruded aluminum frame hold the face rigid in wind.
