hey guys internal led question

I looked but was still confused....

what are the exact bulb sizes for the license plate? and where can i buy leds? any place where you guys all went?

I also want to get some map lights and rear cargo light, what are the sizes for that? and again where can i buy them?

I need sizes for basically all the interior bulbs so i can get comparable leds for them to modernize the interior.

thanks in advance
