Systems and methods for providing a firearm with an extendable light source

Abstract

The present invention relates to systems and methods for making and using a firearm that includes an extendable light source that can be selectively moved closer to and farther from a longitudinal axis of a barrel of the firearm. In some cases, the light source includes a laser or a light bulb, such as an LED. By being able to selectively move closer to and farther from the barrel's longitudinal axis, the light source can be adjusted so that it is able to shine past one or more attachments that are placed on a distal end of the firearm. Other implementations are also described.

What is claimed is: 
     
         1 . A firearm light source comprising:
 a first light source; and   a second light source,   wherein the first source and the second light source are attached to a housing having a lateral outer perimeter,   wherein the housing is configured to be selectively attachable to and detachable from a gun barrel,   wherein the first light source is disposed within the lateral outer perimeter of the housing,   wherein the second light source attaches to the housing so as to be selectively movable between a first position and a second position,   wherein the first position is configured to be closer to a longitudinal axis of the barrel than the second position when the housing is attached to the barrel,   wherein the second light source is connected to the housing and extends laterally past the lateral outer perimeter to emit light outside of the lateral outer perimeter when the second light source is in the second position, and   wherein the second light source is connected to the housing and is disposed in the lateral outer perimeter when the second light source is in the first position.
