cool idea for anyone who read light x reader x L fanfics and has left lights in their room: whenever light is present in the fanfic, change your led lights to red, when L is present, change them to blue. if both are present, you could either make them flash blue and red, or mix both colors and change your leds to purple. when neither of them are present, you can just have it set to wtv u want,
i find it makes the fanfics more emersive!
