Perko Black Base Mount Masthead Light, 12VDC

The Perko Masthead Light is a 12VDC base mount fitting in black plastic with a stainless mounting bracket, giving 3 mile visibility with the bulb included.

Three nautical miles rather than two is the distinction. Visibility range is set by vessel length in the regulations, and a larger boat needs a masthead light visible further off. Fitting a 2 mile light where 3 is required leaves a vessel non-compliant even though the light works.

A stainless mounting bracket rather than a plastic one is what survives being knocked by a sheet, a bag or a boarding ladder at deck level. The bulb is included, which is worth noting since many Perko fittings are supplied without one. Explore more navigation lights.
