Hi Dan, They make a flush mount sternlight that will attach to the transom. But I was concerned that with it set onto the transom it would not be visible through the 180 degree quadrant due to the rudder, ladder and ob obstructing the light for other boats to see. So I mounted mine on top of the port quarter coaming. I have a picture of the setup in the MSOG photosite under boat name "AS-IS". That gets it up high enough to be much more visible. To do the wiring I added 6" access ports to the cockpit coaming both port and starboard. These two are pictured in my photo layout at the MSOG photosite. I also changed out all my lights from the incandescent types to the LED type which use much less electricity. Fair winds, Tom B. ps, after doing all that, I think, all things considered I would have gone with the transom light and risked being run down by some cigarette boat piloted by a guy three sheets to the wind.
