Abstract
Abstract A daytime headlight illumination device carried by a motor vehicle such as a motorcycle or a car for better visibility thereof to other motor vehicles comprising a motor vehicle headlight assembly including a light source and a headlight lens and a shutter assembly located directly in front of the headlight lens and in the path of light rays originating from the light source, the shutter assembly including a plurality of fluorescently colored movable shutter blades and means for moving the shutter blades between an open position for use during nighttime wherein the light rays are passing through only the headlight lens and a closed position for use during daytime wherein the light rays are passing through the headlight lens and the fluorescently colored shutter blades so as to make the motor vehicle carrying the device highly visible during the daytime.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
162 words
A daytime headlight illumination device carried by a motor vehicle such as a motorcycle or a car for better visibility thereof to other motor vehicles, said device comprising in combination; a motor vehicle headlight assembly including a light source and a headlight lens and a shutter assembly located directly in front of the headlight lens and in the path of light rays originating from said light source; said shutter assembly including a plurality of fluorescently colored movable shutter blades, said fluorescently colored blades exhibiting photoluminescence so as to provide enhanced light emission over a given wavelength range, and means for moving said shutter blades between an open position for use during nighttime wherein the light rays are passing through only said headlight leans and a closed position for use during daytime wherein the light rays are passing through the headlight lens and said fluorescently colored shutter blades so as to make the motor vehicle carrying said device highly visible during the daytime.
Claim 2
Dependent Claim
162 words
A daytime headlight illumination device carried by a motor vehicle such as a motorcycle or a car for better visibility thereof to other motor vehicles, said device comprising in combination; a motor vehicle headlight assembly including a light source and a headlight lens and a shutter assembly located directly in front of the headlight lens and in the path of light rays originating from said light source; said shutter assembly including a plurality of fluorescently colored movable shutter blades, said fluorescently colored blades exhibiting photoluminescence so as to provide enhanced light emission over a given wavelength range, and means for moving said shutter blades between an open position for use during nighttime wherein the light rays are passing through only said headlight leans and a closed position for use during daytime wherein the light rays are passing through the headlight lens and said fluorescently colored shutter blades so as to make the motor vehicle carrying said device highly visible during the daytime.
Claim 3
Dependent Claim
31 words
A daytime headlight illumination device according to claim 1 wherein said shutter assembly includes a mounting rim for mounting said shutter assembly on a variety of headlight assembly sizes and shapes.
Claim 4
Dependent Claim
26 words
A daytime headlight illumination device according to claim 1 wherein the plurality of said fluorescently colored shutter blades are horizontally oriented and parallel to each other.
Claim 5
Dependent Claim
25 words
A daylight illumination device according to claim 1 wherein said shutter assembly includes an actuating rod cooperating with said means for moving said shutter blades.
Claim 6
Dependent Claim
25 words
A daylight illumination device according to claim 1 wherein the plurality of said fluorescently colored shutter blades are vertically oriented and parallel to each other.
Claim 7
Dependent Claim
167 words
A daytime headlight illumination device carried by a motor vehicle such as a motorcycle or a car for better visibility thereof to other motor vehicles, said device comprising in combination: a motor vehicle headlight assembly including a light source and a headlight lens and a shutter assembly located directly in front of the headlight lends and in the path of light rays originating from said light source; said shutter assembly including a plurality of fluorescently colored horizontally oriented movable shutter blades parallel to each other and means for moving said shutter blades between an open position for use during nighttime wherein the light rays are passing through only said headlight lens and a closed position for use during daytime wherein the light rays are passing through the headlight lens and said fluorescently colored shutter blades so as to change the white light of the light rays into a more easily seen and brighter color thereby making the motor vehicle carrying said device highly visible during the daytime.
Claim 8
Dependent Claim
167 words
A daytime headlight illumination device carried by a motor vehicle such as a motorcycle or a car for better visibility thereof to other motor vehicles, said device comprising in combination: a motor vehicle headlight assembly including a light source and a headlight lens and a shutter assembly located directly in front of the headlight lends and in the path of light rays originating from said light source; said shutter assembly including a plurality of fluorescently colored horizontally oriented movable shutter blades parallel to each other and means for moving said shutter blades between an open position for use during nighttime wherein the light rays are passing through only said headlight lens and a closed position for use during daytime wherein the light rays are passing through the headlight lens and said fluorescently colored shutter blades so as to change the white light of the light rays into a more easily seen and brighter color thereby making the motor vehicle carrying said device highly visible during the daytime.
Claim 9
Dependent Claim
31 words
A daytime headlight illumination device according to claim 6 wherein said shutter assembly includes a mounting rim for mounting said shutter assembly on a variety of headlight assembly sizes and shapes.
Claim 10
Dependent Claim
25 words
A daylight illumination device according to claim 6 wherein said shutter assembly includes an actuating rod cooperating with said means for moving said shutter blades.
