What light sequence do puffin crossings have?

A puffin crossing has a green light, amber light, red light, and additional amber and red lights that flash. These signals allow for a safe crossing for pedestrians, as the flashing amber and red lights serve as a warning before the signal changes to green for vehicles to proceed. Option A is incorrect because it does not include the additional flashing lights. Option C is incorrect because it does not mention the amber light. Option D is incorrect because it describes a zebra crossing, which has a continuous flashing amber light.
