I have several pictures of hte factory sidelights on MARINERs of that vintage. You will also need to have a 135deg. white sternlight on the stern deck (or transom) visible from aft. and a "steaming light" located on the forward side of the mast (at least 39" above the sidelights) that you can turn on in addition to the sidelights and sternlight when under power. Another option for under power is to use a 360deg white light mounted at the masthead or on a short pole (tall enough to get the light at least 39" higher than hte red/green sidelights) at the stern, you will need to be able to turn off the sternlight while keeping the sidelights on with the 360deg light. If the 360deg light is able to be switched on separate from the rest of the lights then it can also be used as an anchor light.
