I know of two currently here that are out. They are on Davits and were out when the HPS fixtures were still up. Seems like the linemen never checked the inline fuse in the pole.
Yep some of the LEDs on steel or concrete polee are out due to blown fuses or other electrical issues. Never seen fusing for lights on wooden poles, so in this case its either a bad PC or a burnt out driver unit inside the fixture.
They were originally using the existing PC's from the old HPS lights which some were bad so we ended up getting new LEDs that didn't work. They eventually went around and changed all the PC's to those LED specific ones and all seem to be working fine.
