Two 1.5m (5′) lengths of EL wire attached to a Tom Bihn Brain Bag.
You can plug and play EL wire units from many suppliers, but you’ll need to add a Y connector if you want to run a pair.
The 1.5m length gives a slight overlap. The controller sits in the top pocket. The EL wire is attached to the pocket trim using 19mm foldback clips. The clip arms can be easily removed (as shown) or reattached, making it easy to swap out the EL wire as needed — via Youtube
