Simson Brightly hub dynamo front light The Simson hub dynamo headlight Brightly is specially designed for city, trekking and hybrid bikes. The lamp can be switched on or off manually using the handy slide switch on the back. In automatic mode, a sensor in the lamp reacts to light and movement, causing the lamp to light up when you get on your bike in the dark. Thanks to the 'parking light function', the lamp continues to burn for a while when the bike is stationary, which is very convenient and safe in traffic. An additional application is that the headlight can be connected to the rear light of the bike, so that the rear light can also be supplied with power if desired without connecting a second wire to the hub dynamo. The black galvanized aluminum bracket with stainless steel screws and bolts ensures robust quality and a modern look. The powerful 70 lux light column reaches far and is very bright.
