A breakable light witch will flicker when you shoot it.
A more advanced breakable. If you give the glass less than 20 damange, the light will just spark on time, but if you break it, the light will flicker, controlled by a logic_timer. There is also a sprite added to the light. It will flicker together with the light_spot. I added a light entity too, wich will never flicker or getting turned off. I did this because if you broke all the lights the room sometimes would be totally dark. Adding a little bit light all the time, was looking better, but if you don't want that, simply delete the light entitys.
Cubemaps is added to the prefab too.
Its really hard to take some good Screenshots of the lights. Please do not rate this prefab if you havn't tried it yourself.
Use it as much as you want.
Credits is required if you are gonna use this prefab, but you think that this is a problem, please contact me, and we may find another solution.

Good idea and detail, just not very handy for a prefab since the entire room is included when you import it.
Include the room as an example sure, but at least make an actual prefab for the light itself so that you can import as many as you want without entity conflicts via the _&i naming scheme.
