What would you use this icon for?

I have two flights of stairs and a landing in between where I have installed LED strips along the stairs and landing in my house and would like to have in Home Assistant meaningful icons

Give us an example of what this icon might look like.

This is extremely niche and overly literal for a small icon. I don't think this is something we'd be interested in adding.
