On my Orange L, my lights do not retract to the closed position on occasion. But if I open the hood and just touch the mechanical knob inward, then the knob spins on its own and the lights shut. Is there some position that the knob must be in for the lights to work correctly on their own? The knob is in the outward positon now, and if I had to manually roll the lights, I would have to push the knob inward.

No; probably whats happening is, one of the copper bars that makes up the DC motor commutator in the headlight motor, is shorted. This often happens with DC motors by wear which produces copper shards that then touch another bar. As luck would have it, its often the copper bar the system parks on, so the motor becomes non-self-starting. But rotating it slightly brings a 'good' commutator bar to play and after that, motor inertia causes the thing to glide past the no-power point.
To fix, remove the motor, disassemble the end with brushes and run a jacknife bleade between ALL the copper commutator blocks.A spot of grease on each end will be appreciated, since the motor likel has seen no fresh grease since it left the factory. Each commutator baris electrically insulated but if copper smears across, those two get connected & the effect is an open circuit at that point.
