If you have a project where you'd like to be able to detach the wiring, this wire will fit the bill. Its a JST 2.5mm 'free hanging' cable assembly that latches strongly. One wire is marked with a white dashed line. You can't plug these in backwards.

We use these mostly for EL wire. This is the same connector as is on the inverter. It's useful if you're making a Y-connector or want to attach EL wire to some other kind of inverter. 0.1" (2.54mm) pitch JST SM connector on the end

Please note these are designed for use with EL wire/panel/tape which is AC. For that reason, you can't assume that the striped wire will match on the plug and socket sides!
