• Abstract:
  The Texas State Department of Highways and Public Transportation has experienced difficulty in maintaining highway lighting integrity. High pressure sodium vapor (HPS) lamp outages, and problems with starter boards and ballast systems occurred on a regular basis. Many of these lighting failures could not be traced to poor installation/maintenance procedures or to lamp manufacturing defects. Laboratory tests were conducted at the TTI Research Annex at Bryan, Texas, to determine if high pressure sodium vapor lamps (HPS) were subject to vibration. The tests showed that induced vibrational forces up to 2 g caused "blink-out" and structural damage to one half of the lamps tested. The results from the laboratory tests were utilized to set instrumentation parameters necessary to conduct field tests.
