Outside entry light

[Camping family]

What does everyone do for an outside entry light. I can’t believe and didn’t even think about till our first camping trip and went to get into camper at night. That was when we noticed there was no light near the door. Sure it has awning lights on the sides of the rails. But no light at the door. Makes it little had for mom to see those steps. Thought about a solar light at the door but figured it would fall off during travel. Thinking about some kind of light I could mount to the steps. Any ideals from those who had the same problem and found a fix.
