Abstract

Abstract A motorcycle helmet, snowmobile helmet, or other apparel worn by riding a vehicle is coupled with a brake light assembly. The brake light assembly includes a receiver circuit for receiving an encoded radio frequency (RF) signal from a transmitter located on the vehicle. The receiver circuit turns on the brake light for a predetermined amount of time after the brake signal is received. The transmitter is turned off for a second predetermined amount of time after the encoded signal is transmitted. The second predetermined amount of time is less than the first predetermined amount of time. The second predetermined amount of time is advantageously a pseudo random of time. The radio-controlled brake light system advantageously increases noise immunity and spurious illumination of the brake light in response to signals from other riders or operators.
