I have one made by these guys on my boat:
Lopolight products
The previous owner bought it and installed it. I'm way to
cheap to buy that brand myself. It IS a thing of beauty, though, and works well. Looks to be very well made...too soon to tell about
reliability. It also claims to be USCG certified (something you don't find on all
led lights out there). My previous boat also had a combo light. I just converted the bulbs to led on that one (i said I was cheap).
I see Lopolight calls the model that I have only a
power boat light...not for sail. Not sure why. Maybe cause they can't assume that the boat has a separate 135 degree stern light (which mine does).
