EL inverters allow you to drive EL (electroluminescent) wires. This particular EL inverter accepts a 12 VDC wall adapter. The output is terminated with a JST PH connector. You can drive EL wires with them directly, but you may need to re-terminate them. There is also a small switch on the side which allows you to switch between ‘on’, ‘off’, and ‘blink’ settings.
