Introduction
This section describes the L-861SE threshold/end light. The L-861SE threshold/end light is
used to delineate the threshold/end of non-precision IFR runways.
The L-861SE light fixture consists of the following:
— A pair of inner lens doublets (3) coupled with a clear outer globe (1)
— Continuous clamping band (4)
— Inner spring clip (2) to hold two 180-degree inner lens segments
— Frangible coupling (7) that threads into a 1-1/2 12 NPT tapped hole in either a 30-inch
(762-mm) stake assembly or a 12-inch-diameter L-867 base cover plate.
The cast aluminum head and base assembly can be mounted on a standard
L-867 base plate or on a steel stake. Base mounting is easier to maintain and provides added
protection for the equipment. Stake-mounted lights require transformers, cables, and
connectors that are designed for direct earth burial.
Refer to Table 1 for mounting heights.
NOTE: The measurements in Table 1 are taken from the grade to the top of the light fixture.

red/red, green/green, green/yellow lenses.
