Attack the light! suggestions

Hi again guys. As I'm getting new resources to begin DMing shadowdark, I was thinking: what are your most original and fun ways to attack the light? I want to be as loyal as possibile to the spirit of the game, so this Is a concept I am leaning into.

On the other hand, the most obvious way to do so Is to have the enemies literally trying to shut down the light sources, but how do you rule this while keeping It simple? Would an Attack on PG AC+5 work?
