Light bulb moving HELP

Hi!
I was wondering, what would be the best way to make a light bulb moving?
It’s going to be a light bulb attached to a string that swings back and forward, a little creepy feeling (yes, I’m making a horror game).
Should I use animations, rigidbodies etc.

Please help!

I’d use a hinge joint for this. Check out the HingeJoint Script Ref
