White LED Marine Navigation Anchor All-Round Boat Light [USCG ABYC A-16 3NM] [IP66 Waterproof] [Chrome & ABS] 3 Nautical Mile Visibility Fold Down Stern Light for Fishing Boat Yacht Pontoon

smaller then originally thought. very sturdy construction, ample wiring. using for mast anchor light. edit: i will be using this one on stern as its nowhere near as bright as the one i have already on the stern. this light is good enough for the stern. noway at 23-25 ft in the air is this bright enough to be seen 3nm away.

Fits and works great

Not bright at all i dont see them being visable for 3 miles at all but they probable tested them. Made well though. Im not impressed with the output at all.

You cannot simply mount this and meet USCG requirements

You can't change the bulb on this 360 degree white navigation light because it's sealed against water intrusion. It has 18 AWG tinned marine quality wire in a white plastic sheath coming out of a sealed hole in the bottom. Also includes three long stainless steel screws for mounting.
