I'm looking for a new set of lights for my bike. I commute 5,5k one way everyday for the last 3 years. When there is snow or ice I take the bus. At the moment I have a knog blinder mob front light. I'm in the market for something more powerful with better illumination of the road ahead. I'm also up to recommendations regarding dyno hubs and front lights, but keep in mind I'm using an old 80s road bike conversion to Single speed. I really don't want more rolling resistance... Budget is variable, up to 250€ I'd say is ok. To further complicate things I'm from Germany, laws for lights are quite strict, they can't be blinding to other road users.

Any recommendations?
