> I’m surprised there’s no regulation of brightness or “flashiness” for bicycle lights. There is, at least in the UK, though perhaps not the regulation you may want: > The lamps may be steady or flashing [...] but the flash rate must be between 60 and 240 equal flashes per minute (14 per second) and the luminous intensity must be at least 4 candela. https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/407848/Information_Sheet_Pedal_Cycles_Lighting.pdf https://www.gov.uk/government/uploads/system/uploads/attachm...
