I'm not sure if this is the right ng to ask this question..
I apologize in advance if it's not.
My mother is visually impaired and has trouble seeing
her thermostat dial to set the temperature for heat.
I have been trying to find a lighted thermostat dial with
large easy-to-read numbers so she can see where the
temperature is set when she needs to adjust it.
Does anyone have a suggestion for where I might
buy one....or an idea on how to make one?

What about a digital display? The display is much larger than the
mechanical dials. Many choices at your local home improvement store.
