REFLECTOR
Reflectors are used by the military, police, fire departments, construction sites, and on bicycle and motorcycle clothing to increase safety and visibility at night.
When the light is shone on it, the reflector reflects in the dark, creating an artificial coolness, as well as a coolness when the eyes of an animal lurking in the darkness glow.
(It's not like we're just putting in unnecessary LED lights for decoration.)
It's cool that it has proper functions.
Reflectors play a role in increasing safety and awareness at night in military, police, fire departments, construction sites, bicycles, and motorcycle wear. When you shine a light on it, you can feel the artificial coolness of the reflector that reflects in the dark , and the coolness of seeing the eyes of an animal hiding in the darkness shine. (It's not like decorating it with unnecessary LED lights.) It's cool and has proper functionality.
