Moon Sirius Pro Rear Light

The Moon Sirius Pro Rear Light features smart motion and light-sensitive technology and a brake sensor. With a maximum of 350 lumens, this light has five solid or flashing modes to choose from to ensure visibility on errands, the daily commute, or simply when riding as the light begins to fade. It has a built-in reflector to further boost visibility, including from the side, and the charge level indicator makes certain you're never caught short mid-ride with less battery than expected.

Battery life ranges from 3.5 to 35 hours, mode-dependent, and charging is simple with the included USB-C cable. The CNC aluminium heat sink casing absorbs excessive heat and sustains a long working life for this reliable light, which can be mounted to any shaped seatpost with the two O-rings provided.
