Is there a special way to wire lights that can be rotated and rely on the flexing of wires for this to happen?
Some lights fixtures can rotate (as well as tilting up and down) , such as https://www.amazon.com/Nuvo-Lighting...A01RN021D&th=1
That particular light doesn't have a fancy electrical connection that allows the rotation. I relies on the flexibility of the wires. It has a stop that prevents the light from being rotated more than one turn.
