Abstract: A wearable article is described. The wearable article may include a fabric piece, an electroluminescent (EL), and a switch. The EL wire may include a conductor and a light emitting phosphor in contact with the conductor and configured to enclose the conductor and to emit light in response to the conductor receiving power. The EL wire may also include an insulator configured to enclose the light emitting phosphor. The insulator may include a structure configured to attach to the fabric piece. The switch may be configured to control power supplied to the conductor such that the switch controls an operation mode of the EL wire.
