My wife and I wanted a light for the step up to our bedroom in our 2019 22 M, so we ordered a rope light and switch to be mounted in the coach at the factory. Here's a picture of the step light and the switch (on wall above stove) that Winnebago installed. It's a very low amperage light and we leave it on all night so that we don't miss the step going back and forth when it's dark. We really like it:

Great job in getting the factory to install this for you; it looks great.
I did the poor-man's best alternative; I installed four night lights in the four outlets. From Amazon, they are the Sycees Plug-in LED Night Light with Dusk-to-Dawn Sensor:
