When I installed LEDs into my dome light, I reused the original blue sockets. I removed the original bulbs from the blue sockets. I had to bend the wire conductors on the LEDs to allow them to make contact.
But, as I said in my post above, the LEDs never go all the way out. I am going to replace them with the originals.
I'm including some pictures from a post I did. If you look at the 3rd picture, you can see the LEDs are in the original blue sockets.
Hopefully this was helpful.
