The lights along the retaining wall on the 300 & 400 blocks of Wood St work inconsistently. They'll stay on for about 15 minutes and then shut off for about 10 minutes and then they'll come on again.
When high-pressure sodium fixtures cycle in this manner, the problem is an operating-phase (final phase) ballast failure. Replacement of the ballast is the only fix.
