    gives the experiment the green light.

    I think gives the experiment the green light. comes from the traffic light whose "green light" allows people to pass. Doesn't it?

    15)The principal asks the teacher
    if a chicken would be better instead of a pig. But at Mr. Hoshi's insistence, the principal gives the experiment the green light. Mr. Hoshi explains to his class the goal of the project.
