[SCRIPT] Lighting a stove and billboard

[The chaser]

Jens was saying that a way to deactive a billboard be by connecting it a light and setting the light value to zero (fadelightto("light", 0,0,0,true).

It is possible. Place the lights you want lit in the level editor. Copy their names and light values into FadeLightTo("Name of your light", 1, 1, 1, 1, true);
Numbers equals to Red green Blue Alpha - in that order. Connect appropriate lights to their respective billboards.

By lights, you mean lights or lamps?
