Final answer:
Low intensity flashing lights are critical for safety and are mounted on traffic control devices like barricades, drums, panels, and advanced warning signs to alert drivers and pedestrians of potential hazards.
Step-by-step explanation:
Low intensity flashing lights are typically mounted on a variety of traffic control devices to ensure the safety of both pedestrians and drivers. These devices include barricades, drums, panels, and other advanced warning signs. Low intensity flashing lights serve as a visual alert to approaching traffic of upcoming hazards or changes in driving conditions, such as construction zones, accident sites, or school areas. These lights are designed to attract attention and promote caution when regular street lighting may not be sufficient. In situations where there is a significant risk to public safety due to high speeds or frequent accidents, as mentioned in a cause-and-effect paragraph about installing a traffic signal, flashing lights can be a critical component to prevent further accidents and even save lives. It's highly important that all drivers and pedestrians understand the meaning of traffic control devices and warning signs for their safety and the safety of others.
