The adapter bracket generally includes an annular ring having an open interior defined by an interior circumference, an exterior circumference, a top surface and a bottom surface, a plurality of indexing apertures disposed around the interior circumference, and a plurality of clamping tabs disposed around the exterior circumference. The adapter bracket further includes a plurality of ears attached to the annular ring, the ears having a slot for receiving a threaded anti-vibration bushing. The adapter bracket also includes a headlight aiming riser. A headlamp is disposed in the open interior of the annular ring and the annular ring is secured by the clamping tabs to a retaining ring and the annular ring, the headlamp, and the retaining ring are secured to a main bracket by fasteners that engage with the threaded anti-vibration bushings. ## Claims ### Claim 1 A universal adapter bracket for a motorcycle headlamp comprising: an annular ring having an open interior defined by an interior circumference, said annular ring also having an exterior circumference, a top surface and a bottom surface, wherein a plurality of indexing apertures are disposed around the interior circumference of the annular ring, wherein a plurality of clamping tabs are disposed around the exterior circumference of the annular ring, each of said clamping tabs having a hole therethrough; at least two ears depending upwardly from the top surface of the annular ring, said ears having a hole therethrough and a slot for receiving and capturing a threaded anti-vibration bushing; a headlight aiming riser depending upwardly from the top surface of the annular ring, said headlight aiming riser provided with a plurality of holes to secure a headlight aiming apparatus to the headlight aiming riser; wherein a headlamp is disposed in the open interior of the annular ring and the annular ring is secured to a retaining ring by first fasteners passing through the retaining ring and into the holes in the clamping tabs on the annular ring; and wherein the annular ring, the headlamp, and the retaining ring are secured to a main bracket by second fasteners that extend through the main bracket, into the holes in the ears, wherein said second fasteners are in threaded engagement with the threaded anti-vibration bushing. ### Claim 2 (depends on 1) The universal adapter bracket for a motorcycle headlamp of claim 1, further comprising a bezel covering the retaining ring and attached to the main bracket. ### Claim 3 (depends on 2) The universal adapter bracket for a motorcycle headlamp of claim 2, wherein the annular ring, the headlamp, the retaining ring and the main bracket are disposed within a housing and the bezel mates with the housing. ### Claim 4 (depends on 2) The universal adapter bracket for a motorcycle headlamp of claim 2, wherein the bezel has a recess for receiving a primary aiming screw, said primary aiming screw disposed within a coil of a primary aiming spring and engaged with a nut on the main bracket, wherein rotation of the primary aiming screw allows for the aiming of the headlamp. ### Claim 5 (depends on 1) The universal adapter bracket for a motorcycle headlamp of claim 1, wherein the anti-vibration bushings are square-shaped nylon bushings having a threaded axial bore. ### Claim 6 (depends on 1) The universal adapter bracket for a motorcycle headlamp of claim 1, wherein the headlamp is an LED headlamp. ### Claim 7 (depends on 1) The universal adapter bracket for a motorcycle headlamp of claim 1, wherein the headlight aiming apparatus provides a hole for receiving a secondary aiming screw, said secondary aiming screw disposed within a coil of a secondary aiming spring and engaged with a nut on the main bracket, wherein rotation of the secondary aiming screw allows for the aiming of the headlamp. ### Claim 8 (depends on 1) The universal adapter bracket for a motorcycle headlamp of claim 1, wherein the headlight aiming riser is provided with a plurality of locating posts, which engage with holes on the headlight aiming apparatus. ### Claim 9 (depends on 1) The universal adapter bracket for a motorcycle headlamp of claim 1, wherein the universal adapter bracket is formed from a material selected from the group comprising ferrous metals, nonferrous metals and plastics. ### Claim 10 (depends on 1) The universal adapter bracket for a motorcycle headlamp of claim 1, wherein the universal adapter bracket is manufactured by at least one of the following processes: stamping, progressive stamping, milling, CNC machining, additive manufacturing, water-jetting, plasma cutting, and laser cutting. ### Claim 11 An adapter bracket for a headlamp comprising: an annular ring having an open interior defined by an interior circumference, an exterior circumference, a top surface and a bottom surface, a plurality of indexing apertures disposed around the interior circumference, and a plurality of clamping tabs disposed around the exterior circumference; a plurality of ears depending upwardly from the top surface of the annular ring, said ears having a hole therethrough and a slot for receiving a threaded anti-vibration bushing; a headlight aiming riser depending upwardly from the top surface of the annular ring; wherein the headlamp is disposed in the open interior of the annular ring and the annular ring is secured by the clamping tabs to a retaining ring; and wherein the annular ring, the headlamp, and the retaining ring are secured to a main bracket by fasteners that engage with the threaded anti-vibration bushings. ### Claim 12 (depends on 11) The adapter bracket for a headlamp of claim 11, further comprising a bezel covering the retaining ring and attached to the main bracket. ### Claim 13 (depends on 12) The adapter bracket for a headlamp of claim 12, wherein the annular ring, the headlamp, the retaining ring and the main bracket are disposed within a housing and the bezel mates with the housing. ### Claim 14 (depends on 12) The adapter bracket for a headlamp of claim 12, wherein the bezel has a recess for receiving a primary aiming screw, said primary aiming screw disposed within a coil of a primary aiming spring and engaged with a nut on the main bracket, wherein rotation of the primary aiming screw allows for the aiming of the headlamp. ### Claim 15 (depends on 11) The adapter bracket for a headlamp of claim 11, wherein the anti-vibration bushings are square-shaped nylon bushings having a threaded axial bore. ### Claim 16 (depends on 11) The adapter bracket for a headlamp of claim 11, wherein the headlamp is an LED headlamp. ### Claim 17 (depends on 11) The adapter bracket for a headlamp of claim 11, wherein the headlight aiming apparatus provides a hole for receiving a secondary aiming screw, said secondary aiming screw disposed within a coil of a secondary aiming spring and engaged with a nut on the main bracket, wherein rotation of the secondary aiming screw allows for the aiming of the headlamp. ### Claim 18 (depends on 11) The adapter bracket for a headlamp of claim 11, wherein the headlight aiming riser is provided with a plurality of locating posts, which engage with holes on the headlight aiming apparatus. ### Claim 19 (depends on 11) The adapter bracket for a headlamp of claim 11, wherein the adapter bracket is formed from a material selected from the group comprising ferrous metals, nonferrous metals and plastics. ### Claim 20 (depends on 11) The adapter bracket for a headlamp of claim 11, wherein the adapter bracket is manufactured by at least one of the following processes: stamping, progressive stamping, milling, CNC machining, additive manufacturing, water-jetting, plasma cutting, and laser cutting.
