Turning off lamp with wire break

Alright, I was following the TV tut, that has the TV turn off when the cord breaks. I figured you could do the same thing with a light, so I followed the tut, and nothing. I have it set like the tut (different entity names of course) and have everything set right it seems, but it wont work. When I change the light entity, it wont show up, and it makes my room really dark for some reason.

Is it possible to have a light turn off by breaking a cord?

Thanks in advance

Yes, you can. You can toggle most light point entities (no light_enviornments) by LightOn and LightOff.

Going by the tutorial, OnBreak target Light_Entity_Name via TurnOff.

Also, make sure you don't have the Initially Dark flag set.

When you "change the light entity"?

Go figure, something simple. It was in fact via TurnOff. Thanks Joe.

And Lep, I meant change light to light_dynamic, light_dynamic, that kinda stuff
