Dimensions in Inches [mm]

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.

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.
