When are Type A low intensity warning beacons used?

Type A low intensity warning beacons are specifically designed for use at nighttime. These beacons provide visibility and alert drivers to potential hazards in low light conditions, making them essential for ensuring safety in work zones or areas where visibility is compromised after dark. Their design allows them to be easily perceived by drivers in these conditions, enabling quicker reaction times and reducing the likelihood of accidents.

In contrast, other times like daytime or adverse weather conditions such as rain may not require low intensity beacons, as visibility is typically sufficient for drivers to see standard warning signs and other indicators of work zones. Therefore, the function of Type A low intensity warning beacons is most effectively utilized at night when visibility is limited.
