El semáforo translates into the stoplight (or traffic light) is a set of lights on a road that tells drivers when to stop and go. This is usually a set of red, yellow and green lights that control traffic lights. It is important to say that semáforo is a masculine singular noun and el is the masculine singular definite article. So:

IN SPANISH:

Ya no puedes cruzar la calle. El semáforo está en rojo.

IN ENGLISH:

You can not cross the street anymore. The light is red.
