Flashstick

A flashstick is a device similar to a stun baton developed and used by law enforcement on Drall. When the flashstick makes contact with a target, it emits a powerful and blinding flash, helping to subdue the target and reduce its ability to flee. Drall were extraordinarily sensitive to bright light, and it rendered them effectively stunned. It was less effective on humanoids without a sensitivity to light: the subject was blinded, but not incapacitated. It weighed one kilogram and was widely available.
