redlight

Intersection halt signal

Redlight functions as a verb meaning to reject, veto, or halt something—the opposite of greenlight: The studio redlighted the project after budget concerns.

As an adjective, red-light describes districts associated with prostitution and sex work, from the red lights historically displayed in brothel windows: the red-light district of Amsterdam.
