Designed for use on both fixed wing and rotary aircraft, this covert/overt light set is a form, fit, and function replacement for existing incandescent light sets. The design utilizes the single wire connection and footprint of the current installation, and decodes the covert/overt signal from the crew station switch. Utilizing LED technology provides a higher MTBF of 50,000 hours and low-maintenance operation. Covert/Overt Position Lights See specs and features on page 2 ... Navigation (Left/Right) Light Exterior Helicopter Lighting Tail Light Covert/Overt Anti-Collision Beacon Light This light is an integrated visible/IR light utilizing LED technology that replaces the existing rotating beacon and IR ring on a helicopter. The unit provides a universal mounting ring that supports multiple aircraft versions. The LED technology provides an MTBF of over 25,000 hours and no moving parts to wear out. In the visible/overt mode, the light is a normal red flashing anti-collision light that is also NVIS-friendly in accordance with MIL-STD-3009. In IR/covert mode, the lights are only visible with Gen III night vision goggles.
