Good Morning Shipmates

Help please - could anyone please assist me with the the lighting on a Royal Navy Steam Pinnace as shown in the picture, what I need to know is what would the location have been of the stern light ? Also would the lights at the time been oil fired or would they have been DC electric run off a steam generator - enquiring so the I get the right kind of light for my model.

Thanking you in anticipation of you help
