Bicycle reflectors are safety devices attached to bicycles to enhance visibility, especially in low-light conditions. They are typically made of reflective materials that bounce light back towards its source, making the bicycle more noticeable to drivers and pedestrians. Common types of reflectors include those found on the front, rear, and wheels of the bike. These reflectors come in various shapes and sizes, such as rectangular, circular, or triangular. Many countries have regulations that require bicycles to be equipped with reflectors to ensure rider safety. Properly maintained reflectors can significantly reduce the risk of accidents during nighttime or poor weather conditions.
