>>36722770Basically the same idea as Brawly's gym in Gen 3 but using a cone of light, as if the player is using a flashlight, instead of the basic circle. Pic related is a quick mock-up of how it might look if it's even possible.
If that's not possible, getting a flash of light for only a few seconds after defeating a trainer, while the gym is otherwise dark, would also work well.
