The Streamlight SL-SideSaddle USB Hat Light in Yellow is a compact, USB-C rechargeable hands-free lighting system built to mount securely to hats, hard hats, and helmets. Its tough polycarbonate thermoplastic body houses a high-output LED that offers spot, flood, and combined spot/flood beams, while a blue rear safety light helps you stay visible from behind. With up to 400 lumens on the combo setting and multiple high and low modes, it delivers versatile illumination for demanding work environments.

This model is ideal for job sites, inspections, roadside work, and any task where you need reliable light without tying up your hands. The quick-release design lets you detach the light for handheld use without disturbing the mount, and the IPX7 waterproof rating with 2-meter impact resistance means it is ready for harsh weather and rough handling. USB-C recharging and the included lithium polymer battery keep downtime low, reflecting Streamlight’s focus on practical innovation and dependable performance.
