Presented below are some detailed photos of a rare hero illuminating Starfleet Type II phaser pistol prop that was used during the production of the first three seasons of Star Trek: Discovery. This item recently sold as Lot #9 in last month's Prop Store Star Trek: Discovery online auction for an impressive final price of $26,250 (including a 25% buyers premium).
As noted in the auction description, the small circular indicator at the rear of the phaser's top surface controls lights up either blue (to signify "stun" mode) or red (to signify "kill" mode) when its central button is repeatedly depressed.
