hi-vis
Glow for safety
Hi-vis is short for high-visibility, describing clothing or gear in fluorescent colors—typically neon yellow, orange, or lime green—often with reflective strips.
Construction workers, cyclists, and emergency responders wear hi-vis vests or jackets to be easily seen: The whole crew was in hi-vis.
The term works as both adjective and noun.
