If you order the LED module with Quick Disconnect, it will come with the Quick Disconnect connector. However, since the Dark Prophecy LE doesn't have the Quick Disconnect option, you won't be able to swap LEDs. Unless you solder in the other end of the connector into the saber electronics yourself, that is.
Anyhow, you should e-mail them at
[email protected] and ask whether they could add quick disconnect to your saber or not.
If not, you could wait for Ultra's CSO and have him add it as a custom job.
