red light
Intersection stop signal
A red light is a traffic signal indicating stop—drivers must halt until it changes.
By extension, a red light is any signal to stop or prohibition: The project got a red light from management.
A red-light district is an area known for prostitution and sex-related businesses, from the red lights historically displayed outside brothels.
