Report the intersections to the local agency as noted above. Cite it as a safety issue both for when you're sitting out there with traffic flying around you and when you eventually run the light. They will fix it in a hurry. Offer to bring your bike down when the crew is there so they can make sure it works when they're done.
Sometimes, as in my case recently, they dial in full sensitivity on the electrics and call it good, only to find out later, when you go to use the light and complain again that the card is bad and it needs to be replaced.
