Navigation lamp wiring is usually done with conductors with insulation colors BLACK and GRAY. A 16-AWG flat two-conductor or "ZIP Cord" type cable is sometimes used. A source of this cable has been found at PACER GROUP. See

They offer 25-foot lengths for $6.25. Their product code is WB16BK-GY

According to the provided link, that cable is "constructed from annealed bare copper wire." Through experience, I have found when boating in salt water that tinned copper conductors are essential for this application.

TOM--you make a good point. Tinned and multi-strand wire with a high strand count is preferred for marine use. If you find any in the BLACK/GRAY color code, please follow-up with the source.
Use of bare copper conductors can be mitigated by tinning the ends where connections are made with solder. Also, many electrical cables made for use underground (and thus in wet environments) use bare copper wire.
Next time I have my 1990 Boston Whaler boat available, I will look at their black/gray cable to see if it was made with tinned conductors.
