Bulb for nav light

Can anyone decipher the top of the Aqua Signal nav light in the image below and tell me what model this is? It is a bi-colored light. Does Dr. LED make a USCG certified bulb for this light fixture? Do I need a bi-colored LED bulb even though the lens is colored?

Thank you to anyone that can clear this up for me.

Aquasignal TD41 seems to mean it is one of these:

There is not a bulb that is certified by itself. There are only bulb/fixture combinations. Only if the bulb is certified with that exact fixture will it meet approval. None are approved, regardless of what the bulb manufacturers state.

This link shows a letter concerning this from Aqua Signal on post #4

Well worth reading.

Re: Bulb for nav light

Yes, you most certainly need a red LED bulb behind the red lens and a green one behind the green lens. A white LED will barely show through a coloured lens. I had a local fellow make custom LED bulbs for my Aquasignal and it turned out very well- much brighter than the original and a better quality of light (very pure). If you're a bit handy, you can make your own replacement bulbs.

Re: Bulb for nav light

Just keep in mind that if there ever is an accident at night your lights had better be of the proper CG approved type or you could very well be held liable, regardless of who hits who. I sell Dr Led lights and would never recommend that their nav bulbs be used in a fixture that ends up not being approved as a combination.

The best solution is to buy an approved fixture that is Led. This is especially true of red/green lights. Steaming, anchor, and stern lights being white are less of a problem.
