"What's That Light?" is the seventeenth webisode in the series of 34 Kino webisodes.
While walking down a corridor, MSgt. Ronald Greer and Lt. Matthew Scott (and possibly the entire ship) hear the intercom come on and the voices of Dr. Adam Brody and Dr. Lisa Park testing something they just invented. The Kino is on Greer and Scott's faces the entire time. It seems that Park rigged a full duplex interface with the Destiny's communication system and the frequencies got swapped somehow and now everyone can hear their conversation. It seems that they should have tested the thing thoroughly before talking bad about the military personnel, who Brody declares "can't walk without dragging their knuckles" let alone work a simple device. Then Brody notices that a light is on, despite Park claiming that the intercom was off.
- This webisode takes place shortly after the events of the episode "Earth".
- This is a prequel to the episode "Divided".
