The new TrailSight flashlight is a lightweight magnesium alloy handheld flashlight specifically engineered as a secondary light source for trail runners. Available in various attractive colors including, Blue, Orange, White and Green. Delivering up to 1,200 lumens with a maximum beam distance of 530 metres, the TrailSight pairs long-range route finding with low-angle illumination to help runners identify rocks, roots, trail markers, and terrain changes in demanding night conditions.
Powered by NITECORE's NL1840R 4,000mAh rechargeable 18650 battery, it features a direct USB-C charging port for power bank top-ups and user-replaceable versatility, delivering an extended runtime of up to 46 hours (low mode 150 lumens).
Built from die-cast magnesium alloy with a reinforced composite outer shell, the rugged housing is IP68-rated (submersible to 2 metres depth) with 1 metre impact resistance, providing high durability and heat dissipation for harsh trail environments.
At 128mm long and 27mm in diameter, weighing just 121g (including battery), it maintains a near-uniform footprint designed to slip into a pocket, waist pack, or backpack side pocket for easy carry.
530m range beam,, with 46-hour maximum runtime
The primary optical system uses a NiteLab UHi 20 LED generating a peak intensity of 70,347cd, driving a 1,200-lumen beam out to 530 metres in Turbo mode. Tuned to a 4,500K neutral white color temperature, the beam reduces reflections in rain, fog, and snow while highlighting ground texture details, and provides good eye comfort when using the flashlight for extended periods.
Used alongside a primary headlamp—such as the NITECORE UT6, which shares the same NL1840R battery platform—the TrailSight provides low-angle illumination to cast soft shadows across obstacles, improving depth perception on technical terrain.
Features include three brightness levels (including a 400-lumen MID mode running for 14 hours), Advanced Temperature Regulation (ATR), and a sliding physical lockout switch to prevent accidental power toggles during motion or storage.
A specialist illumination tool that stands out for its big 530-metre throw, 4,500K neutral white beam, interchangeable battery system, and die-cast magnesium build in a small lightweight form factor, suited to ultra-distance runners, mountain athletes, and technical night trail navigation, or general purpose use.
