Wild west of light usage makes cycling habits in UK bad as well. Several thousands of lux lights are pointed towards the oncoming cyclsts switched to strobe mode. Rear light are comparably strong and distracting by all the very creative patterns of flashing. People seem to pour out the children of safety with the dirty bath water of flashing lights. Yes, you want to be noticed, yeah, you made it! By dazzling everyone else and divert attention away from any other traffic or dangers. Very stupid practice, making safety worse, not better.

Those flashing lights aren't even road legal in Germany. I never set mine to flash and I'm not in Germany.

I believe flashing lights are actually less safe as it encourages the driver to look AWAY from you. I certainly don't keep staring at a flashing light.
