The ZHENAO Model SY8108 is a powerful dual-light flashlight system constructed from durable aluminum alloy and ABS materials with an IPX4 waterproof rating, featuring a headlight unit measuring 5.8*4.2*4.2CM and a separate battery compartment sized 9*6.2*3.5CM, with a total weight of 213 grams. Equipped with a dual-light source white laser (providing both white light and yellow light) and a taillight with LED red light, this unit is powered by three 18650 batteries (not included) and supports Type-C USB charging with convenient output functionality for charging external devices. The main light features telescopic zoom for adjustable beam focus and offers five modes: LED white strong light, LED white weak light, LED white flash, LED yellow strong light, and a long press to activate LED white SOS for emergency situations. The taillight red LED automatically illuminates in sync with the headlights for enhanced visibility and safety. The device also includes a convenient auto-off function—staying in any gear for 10 seconds allows a single press to turn it off.
