The Core Survival HEL-STAR 4 EXO® offers high visibility, durability, waterproofing, and easy battery replacement in a low profile, snag free footprint. The two operating functions can be user defined in a variety of colors & IR, flash rates and light intensity options. It stays true to the original low profile design for SAR, airborne, K9 and other confined space operations.

As a personnel marker light developed for multiple military and tactical operations, it retains the original low-profile design required by users. The Velcro® interface provides an emergency peel-away safety feature thus reducing potential interference with parachute risers. User friendly tactile sliding switches can be easily operated with a gloved-hand in the blind while the helmet is donned. The HEL-STAR 4 EXO’s built-in security design features a quick switch deactivation, along with a positive confirmation that the unit is OFF to prevent inadvertent battery drain. For additional peace of mind, users have both a positive visual and tactile confirmation when moving between the ON/OFF and function modes.
