I'd have been in the center of the lane at the light. I move to right after the intersection if it's safe to allow cars to pass. If it's a short distance to the next light, I'll hold the lane. If you're in the lane at the intersection, drivers are more aware of your presence. I'll jump the light a bit when safe to do so and I don't find drivers (or cops) have any problem with that. Gets me up to speed faster and helps keep everyone moving. Police may take a different view of that in major metro areas.
