Laser Detonator

The energy pistol is a weapon in the Fallout: New Vegas add-on, Lonesome Road.

Characteristics
This weapon fires a continuous beam similar to that of a laser rifle or pistol, except for the duration. This weapon is similar in looks to a laser pistol, but without the handguard, and also a pad and screen on its left-hand side. It has a green coloration with red trim at the barrel, and a glowing yellow light next to the keypad and screen. It is also seen on the warhead hunter achievement/trophy.
