Designed to be used either of two ways – mounted on a helmet or handheld – the SideSlide C-Clamp Side-Mounted Helmet Light from FoxFury offers a peak output of 200 lumens and a sturdy aluminum housing with strike bezel. Its high, low and strobe settings are controlled by a single push-button switch on the tailcap that's easy to operate, even when wearing gloves. Power comes from two CR123 batteries or one rechargeable 18650 battery, both user-supplied. A rear-facing green safety light helps other personnel at the scene know where you are.
