here's my idea don't mind the shittiest drawing ever
tie two pieces of fish line the the motor knob somehow... punch a hole through it on both sides or something
then tie the line around clockwise and the other line counter clockwise
route them to the cabin and you can just pull on the lines to turn the knob left or right which will raise the headlights up or down
they would automatically rewind themselves aslong as you get clever and make the knob into something like what sewing thread is rolled on
