ACR HL3 Hemilight Auto

The ACR HL3 Hemilight Auto is a compact, rugged survivor locator light engineered to maximize visibility and reliability on inflatable life jackets. Smaller than other approved lights and featuring rounded edges, it preserves the integrity of your life jacket while delivering big performance when needed.

Designed for quick, retrofit installation, the Hemilight 3 can be attached to almost any style life jacket in seconds thanks to attachment loops that accommodate up to 5 cm (2 in) wide webbing. Its marine-grade construction is built to withstand years of use in demanding conditions.
