Sinewave Cycles Taillight

Compact Dynamo Taillight Built for Everyday Riding The Sinewave Cycles Taillight is a small, hard-wired rear light designed for riders who want a bright, reliable signal that is always ready when the wheels are turning. Powered directly from your hub dynamo, it switches on with your front light and quietly does its job on dark commutes, wet shoulder seasons, and long-distance rides. A compact, machined housing keeps the light tucked in close to the bike while still projecting a clear red beam that is easy to pick out from behind. With fully potted electronics and a sealed body, it is built to shrug off rain, road spray, and year-round daily use. Smart Details That Count Dynamo-powered rear LED: no batteries or charging routine to manage. Designed to pair cleanly with modern dynamo setups, including Sinewave front lights. Compact housing sits close to the bike for a clean look and less chance of snagging bags or clothing. Machined aluminum body with sealed, potted electronics for long-term durability in wet conditions. Bright red output aimed to provide clear rear visibility in city traffic and on unlit roads. Simple two-wire connection integrates with existing dynamo wiring harnesses.
