The Nextorch UT41 is a compact, rechargeable signal and marker light that combines white, red, blue, yellow, green and infrared LEDs in one small housing. It is used to mark a person, vehicle or position at night, for team identification during training and airsoft or paintball games, as a safety beacon when cycling, hiking or working next to a road, and for covert IR marking with night vision. There are 13 beacon and flash patterns, and in red and blue flash mode it runs for up to 56 hours. The white LED reaches about 20 m, green 12 m, yellow 9 m, red 3 m and blue 2 m, and the IR LED works at 850 nm. A built-in 500 mAh lithium-ion battery charges through USB-C, with an LED indicator showing charge status. The UT41 is waterproof to IPX8 (2 m), drop tested to 2 m and measures only 62.5 x 27 x 25 mm. It can be fitted to a helmet, to MOLLE webbing or with the universal mount.
