Reflective clothing does not emit light on its own.It uses light retro-reflection to create a luminous effect, made from materials like high-refractive-index glass beads or micro-prism structures. When light shines on these materials, they reflect the direct light back to its source, producing visibility in the dark. This reflective capability ensures that the clothing remains highly visible both day and night. Wearing reflective vest makes the wearer easier to detect by night drivers, regardless of distance or interference from surrounding light. 

Reflective clothing is commonly used in low-light situations such as nighttime, adverse weather conditions, and other environments with poor visibility. Its applications span various fields, including traffic safety, firefighting, mining, construction, and sanitation. 

Due to its enhanced visibility, reflective clothing significantly reduces the likelihood of accidents by improving the wearer's visibility.
