This hard hat safety light easily attaches directly to any Skullerz Hard Hat or Safety Helmet light mount for use as a beacon light. When clipped to the back built-in mount, it will throw red light in four directions to keep workers visible and safe from far distances in low-light conditions. It features a built-in magnet on the back for securely attaching the light to metal on the worksite or for storing when not attached to a hard hat or helmet. Simply detach from the built-in mounting bracket to use as a portable beacon light or to charge. Designed for the utmost safety and visibility in a variety of environments, this safety light has four working modes: high or high pulse for maximum light (22 lumens for 5 hours on high, 10 hours on high pulse) and low or low pulse for maximum life (4.9 lumens for 22 hours on low, 52 hours on low pulse). A one-button switch makes for easy switching between modes.
