The HIRO 50 from Sigma is more than just a rear light: Equipped with emergency and brake light functions, it ensures even greater visibility in dangerous situations.
Here’s how it works: In regular mode, one LED on the HIRO 50 lights up continuously. During braking, all three LEDs of the rear light shine particularly brightly, which can alert following road users to your rapid reduction in speed. In addition, the light has an integrated emergency brake light, which reacts to heavy braking with a pulsating warning signal. This allows critical braking manoeuvres to be recognised earlier – especially in dense city traffic, during fast road bike rides or in poor visibility conditions.
