See.Sense. is specifically designed not to dazzle other road users. Unlike many other lights on the market, See.Sense. avoids using a narrow beam of light, and instead uses a fresnel lens to disperse the light more than 180 degrees. See.Sense. is very bright only when it needs to be - in places where a cyclist is most at risk, such as road junctions, roundabouts and filtering through traffic, or travelling through an underpass. Finally, although See.Sense. is a bright, daylight visible light, we have set the brightness levels at just below that which is used by emergency services vehicles (police, ambulance, fire).
