What is the best color for reflective stickers at night?

This material reflects white light best at night.

White reflective stickers can effectively scatter light at night, making it easier to be noticed. The white reflective sticker has a smooth surface, which can reduce the influence of reflection and increase the reflection effect. Choosing white reflective stickers can better attract the attention of pedestrians at night and increase driving safety. At night, there are white luminous strips on the clothes of traffic police staff, so it is better to stick white reflective stickers at night.

Reflective materials are widely used in various road traffic safety facilities such as traffic signs and markings, prominent road signs, outline signs, traffic cones, anti-collision pipes, as well as car number plates, clothing, shoes and hats, fire protection, railways, water transport, mining areas and so on.
