Recommend an LED replacement bulb for a C921

I want to get some LED replacement bulbs for the overhead lights in my camper. Even thought the manual says the bulb is a CEC1003, I'm glad I took one of the bulbs out because right on the bulb it says C921



I did a google search but found so many different styles wasn't sure what was the best. Also, has anyone ever seen bulbs this style in RED? LED or otherwise? I do Astronomical Observing with telescopes, and keeping your night vision is critical, so while observing I only use red lights. Would be nice to have the option.

Thanks!

    Those are Warm white LEDs.

    The op needs RED LEDs for a special application.
