Abstract
The bicycle light plant includes a front light and a rear light having a set rated voltage, which lights are connected via a current circuit to a dynamo. The current circuit includes a switching controller which lets the voltage of the dynamo pass uncontrolled if it is below the rated voltage of the bulbs and stabilizes the voltage upon reaching or exceeding, the rated value practically without losses onto voltage level corresponding to this rated value. Accordingly, overvoltage at the bulbs can be prevented. Possible excessive output is not taken from the dynamo or is used for charging of batteries.
