We would need to know what kind of bulbs your light uses. The 1142s referenced 
in my link fit some masthead running lights.
If you use a white light in the red-green-white part of the unit you *have to* 
use WARM WHITE. Cool white will NOT produce red and green through the lenses, 
which were designed for a light with a color temperature around 2500-3500K. 
Cool white LEDs are 5000-600K. For the anchor light it does not matter.

Speaking of LED's  I want to replace my mast head tri light and my anchor light 
with LED's.   Can someone suggest a source these kind of LED's that are 
reasonably priced?

Also, they're using high-output (multi-watt) LEDs that need significant heat 
management, hence the fins and aluminum housings on the residential LED 
replacements.  Remember that they're probably rated anywhere from six to ten 
watts, which is a bunch for LEDs.  Without the heat management, they'd smoke in 
just a few hours.

That heat in the home version is caused by the little power supply built into 
the base that down-converts 120volt A/C house current to 12 volts dc.  When you 
run LED's directly off of a 12 volt system, they don't give off much heat.
