I would like to change the light bulb in the room because the bulb died on me. Trouble is, it is fixed to the ceiling and I cannot take the bulb out. I am attaching two pictures here. On one of the pictures, there is a little knobby looking thing on the top and a slit just below it. I tried pressing on the knob/slit and twisting and turning the whole thing, but nothing happened..it moved a bit but did not come loose. How do I go about this?
I also just tried pulling on it (probably not a good idea), but it looked like it might break :)
