Just thought I'd share for others that have the same idea. My 2017 Cardinal 3850RL had all LED lighting through the coach, except for a few. And guess what they were the ones burning out more often, so I replaced all of them with LED replacements. Your situation may be different
Furrion Microwave counter lights(2) - standard "appliance bulb 30watt" -

Outdoor lighting
- Under step amber fixture (1003):

- Amber porch light, White porch light, both sides of coach(1156):

Then, I found a couple of the LED marker lights (2 diode) had one of the diodes burned out. upon removal, I found the amber lights were incandescent upgrades, IOW, the LED fixture plugged into the bulb socket making for a easy swap. The RED lights where hardwired. No big deal, just cut the end off, and solder the connections to the existing wiring and seal.
They are Bargman 59 series:

I hope this helps.
