a braking system, at least one front headlight fixed to the front part, at least one rear tail light fixed to the tail part, and at least one brake light fixed to the tail parts, an electronic control unit of the brake light operatively connected to the brake light adapted and configured to turn on the brake light upon the activation of the braking system, where the electronic control unit is adapted and configured to detect whether the speed of the motorcycle is either lower than or equal to a first threshold speed, and in that case turn on the brake light intermittently. ## Claims ### Claim 1 A motorcycle, comprising: a motorcycle body having a front part, a tail part and a central part between the front part and the tail part; at least two wheels, constrained to the motorcycle body, comprising a front wheel and a rear wheel; a traction engine, constrained to the motorcycle body and operatively connected to at least one of the wheels; a braking system; at least one front headlight fixed to the front part and at least one rear tail light fixed to the tail part; a brake light fixed to the tail part; an electronic control unit of the brake light operatively connected to the brake light adapted and configured to turn on the brake light upon the activation of the braking system; a start-stop system of the traction engine; wherein the electronic control unit is adapted and configured to detect whether the speed of the motorcycle is lower than or equal to a first threshold speed; wherein the electronic control unit is configured to detect whether the start-stop system is in an activated state or in a deactivated state; and wherein the electronic control unit is configured to turn on the brake light intermittently if the speed of the motorcycle is either lower than or equal to the first threshold speed and if the start-stop system is in the activated state. ### Claim 2 (depends on 1) A motorcycle according to claim 1, wherein the first threshold speed is 3 km/h. ### Claim 3 (depends on 1) A motorcycle according to claim 1, wherein the first threshold speed is 0 km/h. ### Claim 4 (depends on 1) A motorcycle according to claim 1, wherein said intermittent lighting has a duty cycle with a light-on time different from the light-off time. ### Claim 5 (depends on 4) A motorcycle according to claim 4, wherein the light-on time is either double or half the light-off time. ### Claim 6 (depends on 5) A motorcycle according to claim 5, wherein the light-on time is 1 second and the light-off time is 0.5 seconds. ### Claim 7 (depends on 1) A motorcycle according to ding claim 1, wherein the electronic control unit after said intermittent lighting of the brake light is configured to deactivate said intermittent lighting if it detects that the speed of the motorcycle is higher than a second threshold speed. ### Claim 8 (depends on 7) A motorcycle according to claim 7, wherein the second threshold speed is greater than the first threshold speed. ### Claim 9 (depends on 8) A motorcycle according to claim 8, wherein the second threshold speed is 5 km/h. ### Claim 10 (depends on 1) A motorcycle according to claim 1, wherein the electronic control unit is configured to detect whether the engine is in an on state or an off state and wherein the electronic control unit is configured to turn on the brake light intermittently if the speed of the motorcycle is either lower than or equal to the first threshold speed and if the engine is in the on state. ### Claim 11 (depends on 1) A motorcycle according to claim 1, wherein the electronic control unit is configured to turn on the brake light intermittently irrespective of the activation and deactivation of the braking system. ### Claim 12 A method for electronically controlling a brake light of a motorcycle, wherein the motorcycle comprises: a motorcycle body having a front part, a tail part and a central part between the front part and the tail part; at least two wheels, constrained to the motorcycle body, comprising a front wheel and a rear wheel; a traction engine, constrained to the motorcycle body and operatively connected to at least one of the wheels; a braking system; at least one front headlight fixed to the front part and at least one rear tail light fixed to the tail part; a brake light fixed to the tail part; a start-stop system of the traction engine; wherein the control method comprises the steps of: detecting whether the start-stop system is in an activated state or in a deactivated state; comparing the speed of the motorcycle to a first threshold speed; turning on the brake light intermittently if the speed of the motorcycle is either lower than or equal to the first threshold speed and if the start-stop system is in the activated state. ### Claim 13 (depends on 12) A control method according to claim 12, further comprising a step of turning on the brake light upon the activation of the braking system and turning it off upon the deactivation of the braking system. ### Claim 14 (depends on 12) A control method according to claim 12, wherein the step of turning on the brake light intermittently if the speed of the motorcycle is either lower than or equal to the first threshold speed occurs irrespective of the activation and deactivation of the braking system. ### Claim 15 (depends on 13) A control method according to claim 13, wherein the step of turning on the brake light intermittently if the speed of the motorcycle is either lower than or equal to the first threshold speed occurs irrespective of the activation and deactivation of the braking system.
