Servo advice needed

I’m working on a droid as my cyberbrick project. I have a rotating dome driven by a servo. The issue now is lighting it.

All the cyberbrick components except the motors are encased in a frame that drops into the body but the leds will need to be in the dome.

My plan is mount the led breakout board in the dome and run the wire down to the board. My concern comes from the dome rotation and twisting that wire too much. From what I read there is no simple way to limit the rotation of a continuous servo. So would the 180 degree servo be my best option and accept the limitation?

I included a cutaway for reference

Your options are either:

  1. Use 180° servo, which should be fine for the the wires to twist at this extent; or
  2. Use a slipring such as the one in Maker Supply but you’ll have to cut and splice the LED wires.

Thanks, that’s what I figured but thought I’d ask in case someone knew another option.

The slip ring would be a really cool solution but I am trying to keep it as much in the included parts and as simple as possible. It’s difficult to ask people to splice wires when the main draw is the ease of use.

Thankfully I’ve kept to only needing 5mm ball bearings for the front foot and a large plastic bearing for the dome beyond what is included in the CyberBrick kit.
