This is a hero version of the phaser I from Star Trek III. Very similar to the rodd.com Star Trek III phaser I own. The phaser has lights and sound. There is a switch that activates the lights. There is a series of four lights next to the switch which remain lit. There are a series of green lights which are in the trigger. A series of red lights comes on flashing from bottom to top. When the trigger is pressed the sound activates and a red LED lights up the clear bar in front.
