Arclight Pedals are legal for use in most countries, including the US. Regulations do vary significantly by country, and even within a country they depend on the conditions of use, including bike type, trail/road type, time of day, etc. Because of that, we recommend that you check local rules to confirm that Arclight Pedals are acceptable based on your individual situation. With regard to Germany specifically, our understanding is that the Arclight Pedals do not meet the StVZO regulations for use on public roads because of the ability to change from steady to flash.
