I've gotten videos of three of some of these neat setups in action.

Don't mind 10 year old me and vertical recording in this one...

Probably a couple others I've seen that I'm forgetting, but I know all of the in-action ones are the only ones I've caught trains at, for sure. I've gotten photos but no videos of at least one other with no street view, in Hillsdale, IN as well, with a GS electronic bell at it.
Hell, I even made my own:

And here's one in someone's house I randomly found with a mini bell on it:

Others I've found on Google Maps that I haven't been able to visit yet:

I'm also aware that Tommy has recorded several bell-only pedestrian crossings in Illinois, especially on CN and BNSF lines. One such even has a GS type-3. In case you couldn't tell, I'm really in to these crossings, lol. Sorry for not embedding the YT links, I had to use mobile links. :P
