Narrative:

City of san francisco is responsible for ramp construction and setting up barricades to prevent aircraft from taxiing in wrong areas. South of taxiway M there was a wooden barricade with 4 lights laying flat on the ground. The 4 lights were inoperative, and the barricade laying flat is hard to see. I almost ran over it, needed landing lights to see it.
