As of 2007 the normal three section traffic signal weighs about 20 lbs.
Older ones weigh more due to metal being used instead of plastics.
A larger concern is what holds the signal up. If its a cable and it breaks it can be hazardous. If its held up by a mast arm, a serious accident could cause it to crash in the intersection. As a rule, Traffic signals are manufactured to weights and specifications that are deemed safe by the INTERNATIONAL MUNICIPAL SIGNAL ASSOCIATION. Traffic signals rarely fall on their own.
However a storm or a wreck can cuse them to come down.

Certainly, there were mechanical traffic signals that preceded traffic lights, not to mention traffic officers who once stood at busy intersections to direct traffic on a regular basis.
