Through acceleration sensors, the EVO21 detects when you slow down or come to a stop — then the brake warning lights on the back of the helmet are automatically activated. A handlebar remote control can be used to activate the turning lights: this means you don’t have to take your hands off the handlebars to give a hand signal. Instead, the flashing LEDs on the helmet signal that you want to turn. For additional visibility, the front light of the helmet not only beams in the width, but also at an angle of 45° in the height — this ensures that you are still recognized by oncoming traffic even when you are bent over in a sporty position and looking down.
