Red lighted buoys are almost always Port Hand buoys, red and are "can" shaped. Normally they would have a "can" shaped topmark as well but in this photograph the topmark is missing. At night they may exhibit a red flashing light with varying flashes to aid identification. These would be left to port when entering a channel, port or harbour. If channel buoys are numbered port hand buoys will have even numbers with  number 2 being the first one to mark the channel at its outer end. On the chart they are annotated R.
