Patent ID: 8437079

Claim:
An apparatus, comprising: an assembly including: a substantially tubular body having an inner surface and an outer surface, wherein the inner surface forms a first passageway extending through the substantially tubular body; a first portion including one or more components disposed within the first passageway and connected to the inner surface, wherein the one or more components of the first portion include a reticle, a light-emitting diode, and a circuit board including a processor having a program, wherein the light-emitting diode is connected to the circuit board, wherein the program controls the light-emitting diode to emit one of at least three user-selectable colored lights upon the reticle; and a second portion including one or more components arranged upon the outer surface of the substantially tubular body, wherein the one or more components of the second portion includes at least one actuator connected to the circuit board, wherein actuation of the at least one actuator provides an input to the processor to cause the program to control the light-emitting diode, wherein the at least one actuator includes a first actuator and a second actuator, wherein, upon a first, simultaneous depression of both of the first actuator and the second actuator less than a period of time, the program of the processor provides: means for actuating a multi-color mode of operation of the light-emitting diode for causing the one of at least three user-selectable colored lights emitted from the light-emitting diode to be a mixed color light.
