Blinking / flashing bike lights were kind of OK when they were in the 10-20 lumen range. But nowadays even the cheap ones are on the order of several hundred lumens, which is a completely different game. It is possible to buy a 1000 lumen light for around 50 EUR (Magicshine), now consider that a single car headlight is around 1500 lumens... These lights have no cutoff beam. The problem is not even cars though, but other cyclists. Even with a cutoff beam it is easy to blind oncoming traffic if the light is not setup correctly. Flashing, it should be illegal.
