The answer is: El semáforo.

Explanation for each option:

1. La ambulancia: This means "the ambulance" in Spanish. An ambulance is a vehicle used for emergency medical services, not a set of lights above a street.
2. La multa: This means "the fine" in Spanish. A fine is a monetary penalty for breaking a law or rule, not a set of lights above a street.
3. El semáforo: This means "the traffic light" in Spanish. Traffic lights are the set of lights that hang above or beside a busy street to control the flow of traffic.

Therefore, the correct answer is "El semáforo."
