Design of Turn and Brake Lights of Bicycles Using Advanced Wireless Transmission

Bicycles usually are not equipped with electronic sensors and lighting, which are employed in motorcycles and automobiles.Therefore, it is not easy for riders to monitor the operational status of bicycles.To overcome this problem, in this study, we developed a wireless safety light system for bicycles, with a particular focus on turn and brake lights.The system is used to signal for turning, lane changing, slowing down, and stopping, which also increases the visibility and predictability of bicycles in traffic.Two ESP32 modules were adopted for Bluetooth-based wireless transmission to ensure the system's practicality and affordability.The lighting system is easy to install and maintain at a low cost.By integrating innovative technology, an affordable and cost-effective solution is offered to enhance safety for bicycle riders and other road users.
