Chad, you're doing all the hard work for me
I've planned on eventually replacing my gauge lights with LED's but haven't looked into it enough yet to see if they have plun-in replacements...turns out they do.

And my next thought was the LED tail lights because the wagon tail lights are so puny. So thanks, I will be saving this thread

Now, I'll do a little of my own legwork to find some LED dome light replacements.
