Alert
Lezyne’s latest lights incorporate the latest Alert technology. When the cyclist slows down, the light will illuminate as a kind of brake light. Then the light will give a clear flash pattern once the cyclist is stopped to alert riders or vehicles. The light will return to the previous output modes once the cyclist will continue their ride.
StVZO
Germany has special legislation for bicycle lights. This means that bicycle lights must meet different requirements than bicycle lights in the Netherlands or other EU countries. StVZO lights may not flash and these lights have greater side visibility.
