Hi Frank, welcome to our happy band. We'll let you slide with your intro post in General Discussion. This isn't like some forums.
I highly recommend replacing ALL your interior lights with LEDs. I did it several years ago. Just make sure you get SMD/SMT type lights instead of the ones that are in small "bumps". The SMD/SMT lights are brighter and more reliable.
There are many sources now. A place I've always liked is SuperBrightLEDs.com, because they list the lumen output as well as the color temperature of their products, and, they will replace any that are defective. They ARE somewhat more expensive than some other sources however.
For the interior lights, you just need ones that will fit into the sockets in the fixtures. Mine are all flat panel type lights with 9 LEDs per light. You can also use ones that look more like the incandescent bulbs you are replacing, as long as the light distribution is 360 degrees. Stay away from any bulbs with a color temperature above 5500K. Higher color temps will be bluish, and will be hard on your eyes.
