See if you can find out what the local culture is and what law enforcement is like. The police started to give tickets to cyclists for running red lights a couple of years ago. But it's a big city, and the police can't be everywhere, so most people don't stop at lights most of the time. I'm a very cautious cyclist, so I go slowly at red lights, and I'm careful (1) not to inconvenience anyone with right of way and (2) not to scare anyone. But I do break the law. Enforcement is very spotty. I have even broken the law in front of cops in hopes of getting stopped, but I haven't been stopped yet. I even once rode while drinking from a beer bottle. Nothing, but there were no cops around at the time.

Let me say to folks in the western US who think what I describe is deplorable. When in Rome, do as the Romans do. You have no idea how chaotic things are here. We have a different attitude towards law and order here. Your way works for you. Our way works for us.
