Hi,

The easiest way to create the effect would be exchangable textures for every state of light set up.

Another way would be hiding (or creating in realtime) models underneath the unlit lights that have a lit texture on them. Then either animate them to hover over the unlit version of themselfs or create them via code during runtime.

Another way would be shaders, but thats not a beginners way.

I would highly recommend to create this stuff by yourself instead asking others to do it for you. its harder and more time consuming but you will learn quite a bit about models, textures, meshes and problem sollution that way.


just give it a try,
cheers
