The sighting system further includes a light source. The system additionally includes a switch which completes a power circuit that provides power from the power source to the light source when activated, and a conduit configured to transmit light from the light source to the sight of the firearm. The sighting system includes a feature to deactivate the light source when the firearm is holstered or in another stored condition. ## Claims ### Claim 1 An illuminated sighting system for providing at least an illuminated front sight of a firearm comprising: a power source held by a holder within a compartment of a firearm; a light source housed within the compartment in which the holder is provided or within another compartment of the firearm; a power circuit that provides power from the power source to the light source when activated; and a conduit configured to transmit light from the light source and provide at least an illuminated front sight of the firearm, the illumination generally directed at an operator of the firearm, wherein the compartment within which the power source is held by the holder is a drop-in unit insertable in a portion of the firearm. ### Claim 2 (depends on 1) The illuminated sighting system of claim 1, wherein the holder comprises one or more clips configured to retain the power source, and each of the one or more clips extending upwardly from the perimeter of the holder so as to contact at least a portion of a lateral side of the power source. ### Claim 3 (depends on 1) The illuminated sighting system of claim 1, wherein the holder is disposed atop a printed circuit board, and the light source comprises a light emitting diode which is mounted to the printed circuit board. ### Claim 4 (depends on 2) The illuminated sighting system of claim 2, wherein the one or more clips include a plurality of clips spaced along the perimeter of the holder. ### Claim 5 (depends on 1) The illuminated sighting system of claim 1, wherein the power circuit comprises a switch configured to maintain the power circuit when the firearm is in a first state and break the power circuit when the firearm is in a second state. ### Claim 6 (depends on 5) The illuminated sighting system of claim 5, wherein the power circuit does not include a manual on/off switch. ### Claim 7 A method of modifying a firearm equipped with front and rear sights, comprising: affixing a compartment to the firearm, the compartment housing a light source and conduit, the conduit configured to transmit light from the light source and provide an illuminated front sight of the firearm, assembling the compartment with a holder retaining a power source within an interior of the compartment, and providing a switch which completes a power circuit to effectuate supply of power from the power source to the light source when activated, wherein the compartment is a drop-in unit insertable in a portion of the firearm. ### Claim 8 (depends on 7) The method of claim 7, wherein the holder is attached to a printed circuit board, and the printed circuit board comprises a plurality of connection points for attachment to the compartment. ### Claim 9 (depends on 7) The method of claim 7, wherein the holder is configured to grip the power source via a plurality of clips on a perimeter of the holder, each of the clips extending upwardly from the perimeter of the holder so as to contact at least a portion of a lateral side of the power source. ### Claim 10 (depends on 7) The method of claim 7, wherein the power circuit does not include a manual on/off switch. ### Claim 11 (depends on 7) The method of claim 7, wherein the switch comprises a variable transducer configured to output a voltage that varies in accordance with proximity to a magnet. ### Claim 12 (depends on 7) The method of claim 7, further comprising inserting the drop-in unit into a top of the firearm, and covering the drop-in unit with a cover. ### Claim 13 (depends on 7) The method of claim 7, wherein a top of the firearm comprises a slide, and the drop-in unit is provided at an upper portion of the slide. ### Claim 14 An illuminated sighting system for providing at least an illuminated front sight of a firearm comprising: a compartment structured to secure a power source within the compartment; a light source housed within the compartment in which the power source is secured or another compartment of the firearm; a power circuit that provides power from the power source to the light source when activated; and a conduit configured to transmit light from the light source and provide at least an illuminated front sight of the firearm, the illumination generally directed at an operator of the firearm, wherein the compartment in which the power source is disposed is configured as a drop-in unit which is inserted in a top of the firearm. ### Claim 15 (depends on 14) The illuminated sighting system of claim 14, wherein the compartment is configured to mate with a portion of the top of the firearm. ### Claim 16 (depends on 15) The illuminated sighting system of claim 15, wherein the compartment is configured to mate with the portion of the top of the firearm via a stabilization member. ### Claim 17 (depends on 15) The illuminated sighting system of claim 15, wherein the compartment is covered by a cover attached to the top of the firearm. ### Claim 18 (depends on 14) The illuminated sighting system of claim 14, wherein the top of the firearm comprises a slide, and the drop-in unit is configured for insertion into an upper portion of the slide. ### Claim 19 (depends on 1) The illuminated sighting system of claim 1, wherein the drop-in unit is provided as a standalone unit, and an outer surface of the drop-in unit is exposed to an exterior. ### Claim 20 (depends on 7) The method of claim 7, wherein the drop-in unit is provided as a standalone unit, and an outer surface of the drop-in unit is exposed to an exterior.
