Are there caps lock layout switches with a light bulb?

Question

macOS

I want that when switching the layout by caps on the clave, the light in one of the layouts would light up. To do this, I made a small program that, when switched, changes its state depending on the layout.
Could you somehow do without such a bike? There must be an easier way that I don't know about.
It is necessary under Mac OS X and Windows (in both axes I did not find how to do this without perversions).

For windows - no idea, but for poppy - pihto.com/kirgudu
Works with Punto Switcher without problems.

Answer 2

Under OS X I use the Lipton layout . Technically, there is no language switching - just different letters in the same layout. Practically - the same switching on the caps with a light bulb.
I won’t tell you under Windows - there is no keyboard with a light bulb, so I use a simple software, the name of which I don’t even remember.

Answer 3

Try this little thing: download.ru/products/capslang
Small size, does exactly one thing: switches the caps layout.
I've been using it for several years, no complaints.
