4 way switch with pilot light for garage

We closed in part of our garage to add a hall to another room. We have a 4 way switch that controls the lights in the garage (that I wish I would have moved before we added drywall) that is now separated by the new wall. I wanted to add a pilot light to the 4 way switch so I can see when garage lights are on.

I can't find a 4 way switch with a pilot light. Does anyone know if/where I can get a 4 way with pilot light? If not does anyone have any ideas on how I could add a pilot light (easily)?

Here is a diagram I created to try and explain
