2 Way Female to Female Cable (20cm)
Used for connecting to the 2 way neon headers on the RemoteSystem driver board. You could opt to cut in the middle and use your own cable extension to make the final actual connection to the neon lamp. Then you will only need 2 such cables per clock.
Each end has a female connector with 0.1" pitch. Colors may vary.
Neon lamps are available here
