I got a set of 4 of these (seasense) and ran them under the gunnels.
I also bought a bulb style for the cabin.
Like the one you showed. Very nice....
Easy job and they are ""awesome"" for night fishing.
(Best day i had this fall)
One more on the stern light and that does it.
Next year thinking of a bow mount spot light too
Not sure how to make that work (YET).....
As I intend to take more night excursions.
