Dynamic Light placing and control

[MSL]

Hi,
My augmented reality app is supposed to load different architectural models. One of the feature in my wish list is to place lights and user should be able to control the lights(on touch toggle on and off).
The tricky part is different models will have lights in different places. Now, how can I add lights in a particular place at the run time and bind them to onTouch events.

For simplicity, lets say I have 2 model; bed room and living room. When I load bed room model bed lamp and other lights should be placed at respective places. Similarly, when I load living room it should place lights in respective area.

I'm not sure what the actual question is here...if you want some light sources in the scene, then just add them...
