Quick check idiot lights

[Jeff396]

I was noticing while mowing the lawn the other day that the three bottom positions of the idiot lights on the instrument panel don't seem to do anything. The one on the lower left looks like one that should illuminate when the lights are on. The manual makes no mention of these bottom three lights. Is this a case where the same idiot light setup and instrument panel is used for multiple tractors but these lights are just not used on the B7500HSD?
