If you use an LED behind a colored lens, you do need to use the same color LED as the lens in order for the correct amount and wavelength of light to be projected. While using a white LED will ďlookĒ OK, youíre wonít have as effective a light as you would using the specified incandescent bulb. Search the COLREGS- the Coast Guard has very specific requirements for the type of light (the beam cast, not just the fixture) for each nav light.
Google for Running Lights LED replacement. Youíll see that there are specific LED bulbs which fulfill this need. HOWEVER, the USCG does NOT approve of this swap,meaning the lights arenít certified except with the original bulb. As someone mentioned, itís not as though a Coastie is gonna bust you for that swap. More of a concern would be, ďDo I want to be SEEN?Ē
I have the same issue on my boat, and I really donít like the look of the new LED fixtures. I prefer the Perko-style with nice, big glass colored lenses. Hella type 2984 nav lights, now discontinued but still available, have the classic style are are certified for up to 65í, or 2nm. My boat is 38í but Iíd rather be seen further away than necessary.
