Default LED light replacement for running lights

I found the appropriate base and size LED replacement for my running lights.

Has anyone used the - LED BAY15D as a replacement yet? The existing bulbs in my lights is labeled as a 25W bulb and I wonder if this LED will be as bright?

Also - it seems that many of these LED replacement bulb online retailers are recommending a red LED and green LED instead of white when the LED will be inside a colored lens. Their reasoning is that more of the light is transferred through the colored housing.

If that is the case....why did we ever use white bulbs in the first place?

I am going to be switching my nav and anchor lights very soon. Let me know how it works out! My last vessel I changed the entire fixture out, I was wondering about just the light though.
Thanks

LEDs put out a different spectrum of light than an incandescent bulb. Remember, white light is made up of all the colors of the spectrum. So a white incandescent bulb behind a green lens will have all but the green light filtered out. Same with Red.

a "white" LED does not have the same level of red and green in the "mix" so a much lower level of light is transmitted through the lens.

So yes, you need red and green leds (which put out (obviously) more red and green light than the white ones.)

You can replace the bulbs with LED bulbs, but you may not meet USCG requirements for visibility for your vessel. Secondly, you'll still have bulb contact corrosion issues. If you can manage it, replace the whole fixture with a quality brand to improve reliability.

Great explanation that thank you for the reply!


I have a quality brand and Ive never had an issue with reliability or corrosion. Luckily. My only intent here is to reduce the electrical draw on the boat. Im moving almost everything that I can to LED. All I have left are the engine room lights and running lights.

I don't think I'd worry with changing out the nav lights; the only time you'll ever have them on is when you're moving and the engine is running.

Not really. Nav lights are on when drifting at night (which we do) and the anchor light would be replaced if I do the nav lights and obviously that is on when the engine is off. If I do one, Im doing them all.

Main advantage IMHO with led nav lights is that they're sealed and less likely to leak causing issues. I will say do all your nav lights at the same time, saw a boat with led port/starboards and incandescent steaming light was kinda hard to tell if it was one boat or two close to each other.

Here's a cheap way to change over if you have festoon running lights. Get some green and red festoon leds from china and buy some 5 minute epoxy. Coat the festoon with the epoxy seal every thing except the ends that make contact. Make sure you get the epoxy up into the ends of the metal as pictured. I have been using these for about 5 years now the bulbs are only pennies so get several. the white one also work if you have the colored lenses but the colored ones are brighter. Hope this helps some save some bucks$$$

I went new LED running lights and, as recommended, I used green and red LED bulbs for their respective location.

On the panel, the difference in draw is very measurable and worthwhile. From a brightness standpoint - its a no brainer. The new lights are significantly brighter. Very worthwhile upgrade.
