Description

The SIGMA HIRO 50 LINK Rear Light is a connected LED rear light designed for commuters, road cyclists and gravel riders seeking maximum everyday safety. StVZO-approved, it provides visibility from up to 500 metres away, with excellent side visibility.

Its intelligent brake light function uses a built-in accelerometer to detect braking automatically and instantly activate all three LEDs. A pulsing emergency brake light also activates under hard deceleration, making you more noticeable to road users behind you.

Its standout feature is SIGMA LINK connectivity, which intelligently pairs the rear light with compatible SIGMA LINK front lights. Both lights switch on and off together, and the rear light’s battery level is displayed directly on the front light. The SIGMA RIDE app pairs via Bluetooth in seconds, letting you check the charge, name devices and install firmware updates.

Rechargeable in 3 hours via USB-C and offering up to 11 hours of battery life in Eco mode, it fits almost any seatpost without tools using its flexible silicone mount. Compact (30 g) and IP44 splash-resistant, it is ready for rides in all weather conditions.
