Tactical IR LED Signal Light. It is a portable IR LED signal light designed for tactical, emergency, and other military operations. With the 850nm IR LED, the GT-AAA IR emits a distinct infrared image with the aid of night vision devices and provides three different modes from high, low to strobe. Applying the exquisite molding process of sealing glue, its body performs an excellent waterproof effect of up to 200 meters in depth and allows an all-round viewing of 360° illumination. The only press button onthe top can be easily found and activated. Equipped with the GTK, GT-AAA IR can be widely attached to OPS-CORE ARC helmets, 1'' webbing (such as MOLLE/PALs webbing) and any Velcro loop surfaces, making it a durable and useful tool for signaling tasks during tactical, military, search and rescue use.
