Strictly speaking, that's not true. You don't need to live with a white LED to replace the bayonet mount white incandescent bulb.
When I installed my 5 mile tricolor and anchor light fixture, the guy at the LED supplier (as I said, I think it was Dr.LED) asked if I was using a Hella or an Aqua Signal light. Seems both use the same white bayonet bulb. But the socket is oriented 180 degrees differently in the two fixtures. When my bulb came, it had green LEDs behind the green lens, red behind red, and white behind white. I think the seller called the Hella vs. Aqua Signal specific bulbs right handed and left handed bulbs, but the bulb matches the galore of the LED to the lens for maximum light output. 'Couse I had to use a white LED bulb for the anchor light.
