Meaningless, unless you specify the current!

Use an LED anchor light if you really intend to use this thing. An anchor light stays on all night. The LED uses about 10 times less power, needs a much smaller wire, and you'll still be able to start your engine after a long weekend on the hook when you forgot to turn it off!

Good idea, but depends on budget. The USCG certified LED anchor lights are fairly expensive.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Huh? For a 1 amp load at 100 feet you could technically run 18 AWG but this would not satisfy the E-11 minimum 16 GA standard or the fact that they want a 3% voltage drop for nav lights not 10%.

100' of 14/2 for an single Aquasignal 25 drawing .8 amps is fine and well within ABYC specs and yields a 1.72% VD.

Yes, which is why I use it in conjunction with a USCG approved masthead light.

My comment on cost was referring to the LED fixtures.

You can get LED replacement bulbs for the Davis Mega Light. Plus the light has a photo cell that turns it on and off.

Has there ever been anyone cited for using the Davis Mega Light for an anchor light? Ever?

Again, it isn't whether anyone has been cited...but rather what would happen in the case of an accident.

If you're hit when using non-certified lights, the defense can easily claim you are at least partially at fault, which has happened. Expert testimony about lights is expensive and if you have certified lights, that gives the idiot who hits you one less way of weaseling out of responsibility for the accident.

Sorry Dog, it's a non issue in my book. I refuse to live my life worrying about what might happen in some hypothetical court case after some hypothetical accident.
In my mind, that's kinda like letting the terrorists win. I've got better things to worry about.

The Mega light is a lot brighter than the non coast guard approved kerosene light that I used for an anchor light for many years with no problem.
