Simson Luminous information hub dynamo The Simson hub dynamo headlight Luminous is specially designed for city, trekking and hybrid bikes. The lamp can be switched on or off manually by means of the convenient slide switch at the rear. In the automatic position, a sensor in the lamp reacts to light and movement, which turns the lamp on when you get on your bike in the dark. Thanks to the 'position light' function, the lamp stays on for a short time when the bike is stationary, which is convenient and safe in traffic. An additional application is that the headlight can be connected to the rear light of the bike, so the rear light can also be supplied with power if desired without connecting a second wire to the hub dynamo. The black zinc-plated aluminium bracket with stainless steel screws and bolts ensures a robust quality and a modern look.
