Moon Helix Pro 150 Lumen Rear Light

The Moon Helix Pro is a 150-lumen rear light with the intelligence of Moon's top models: an ambient-light sensor swaps to a bright day flash in daylight, and motion sensing dims the light when you stop and switches it off when the bike is parked. The 35 g CNC aluminium body is waterproof to IPX7 and the Variable Lumen System lets you adjust output within each mode. Seatpost, saddle rail and belt clip brackets are all included.
