I ordered these replacements for the 921 wedge base bulbs on eBay from this vendor -

For the ceiling lights:
10pcs T10 194 168 921 Bulb Lamp 9-5050 SMD LED Light,Warm White #Y
For the fixtures over the bed, sofa and bunks:
10x T10 194 168 921 W5W Bulb Lamp 6-5050 SMD LED,Warm White Y
I placed my order on Friday and a have confirmation tracking no. that they are on their way.
Based upon many conversations on this forum and others, I found that the Warm White would be better for our needs and that it should be close to the bulbs we currently use. Also, I ordered the flat style because all of the LEDs will be facing downward anyway. We have a wall sconce and dinette fixture that require the 1056 bayonet-style bulb but I have not found a product that is reasonable since we require three.
Since we plan on dry camping at times, we want to save on our battery. And the heat from the halogens is too much.
Good luck.
