Standards For Strobe Light Installations

See document history

The safety of the traveling public and Department employees is one of the Department's primary goals. In order to make our equipment more visible, the installation of strobe lights has been adopted by the Department.

The chart listed below sets the Department's policy for the minimum number, color and position of strobe lights for each equipment type. District Engineers or Department Heads may, on a case by case basis, authorize the use of additional lights if they feel a situation warrants their use. When additional lights are authorized for equipment, the State Equipment Management Administrator must be notified of the number and color of the additional strobe lights either by letter or email.
