Application:
The Dialight Vigilant L-864 Infrared (IR) LED based medium intensity
obstruction light incorporates both Red and IR LEDs in a single unit.
These lights ensure visibility around military bases, airfield
perimeters, buildings, towers, and other obstructions for aircraft pilots,
both during normal flight or when aided by Night Vision Systems. Night
Vision Goggles (NVGs) and Aviator’s Night Vision Imaging System (ANVIS)
often employ Class A, B, and C filters. These filters can reduce the
responsivity to light in the visible spectrum.
The Vigilant IR
overcomes this obstacle by combining visible red LEDs and IR LEDs in a
single unit.

Vigilant® L-864 Infrared (IR)
LED Based Medium Intensity
The Dialight Vigilant L-864 utilizes a unique optical, mechanical, and
electrical design. This allows for efficient, low-power product with mini-
mal ground scatter. The D464 has extremely low RF interference and is
ideal for the most difficult environments, including “hot” AM
towers.
