There is not much voltage drop considering the current draw of these is
typically 1/4 amp, if it lit the old 10W or 25W bulb, it should be OK. I
bought an anchor light bulb and a bunch of cheap $6 bulbs from Mastlight.com,
failure rate 90% in first year. They do cheerfully replace, but I think
mastlights need surge suppression due to location as compared to lightning.

Wow! They're *much* cheaper than the one I installed (I put on a Lopolight --
if I were redoing it, I'd definitely consider the Signalmate).
Current draw and the required cable gauge are the only things that would make
me go for 2 rather than 3nm. TBH though, the draw on most LEDs is so low, that
I wouldn't worry about the battery drain. Voltage drop may be an issue - *some*
LEDs fail to work it they don't get the required voltage -- unlike tungsten and
halogen lights which gradually dim. I suspect that even small gauge will work
-- in my installation after some concerns about the roundtrip wiring distance
from the battery to the top of the mast (on my N41 its something ridiculous --
wayl over 100 ft), I remember the deciding factor being the mechanical
strength of the cable rather than its electrical properties.
Do you already have cable installed? This link:

should let you work out what cable you need.
Also, if you mount it on the top of the mast -- be sure there's enough
clearance that its visible close by -- I had to make a riser for mine.
