The Simson 'Brightly' hub dynamo headlamp is a hub dynamo headlamp specifically designed for city, trekking and hybrid bikes. The lamp can be switched on or off manually by using the handy round switch on the back, but it can also be set to the automatic position. When the lamp is in the automatic position, a sensor in the lamp reacts to light and movement so that the lamp knows whether it should light up or not. The lamp is also equipped with 'steady light'. This keeps the lamp on for a while when the bike is not moving, which is very handy and safe in traffic. The Simson Hub dynamo headlight 'Brightly' has an extra application to connect to the rear light of the bicycle. In this way, the rear light of the bicycle can also be supplied with power without connecting a second wire to the hub dynamo. The Simson 'Brightly' hub dynamo headlight has a powerful beam of 70 LUX. To ensure the lamp cannot overheat due to the high light output, it is equipped with an aluminium cooling plate on top. The black galvanised aluminum bracket with stainless steel screws and bolts ensures a robust quality and a modern look.
