Star Trek: Voyager, Bio Dampener (hero version)

original movie prop

This camoflage device was used in the episode "Dark Frontier". It is a hero device that has two flashing lights which are activated by a hidden switch. The lights are located behind the clear plastic on the right of the piece. This device was invented by 7 of 9's father to hide himself from the Borg when conducting research on their vessel, and was later used by the Voyager crew when they went aboard a Borg vessel.
Screencap from "Dark Frontier". These props are rare as most of them were repainted silver and re-used in the Star Trek series "Enterprise".
