This mini buzzer is an audio and light alert device designed to work with the blind spot detection system. It triggers both visual and auditory signals when a vulnerable road user, such as a pedestrian or cyclist, is detected within a dangerous proximity. The light indicator can support multiple visual prompts, while the buzzer provides variable frequency sound alerts. This system enhances pedestrian safety by warning them of potential hazards in the surrounding area, helping to prevent collision accidents. It operates in compliance with the specifications outlined for advanced blind spot detection systems.
