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.
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!
