Abstract
Abstract The usual high-beam and low-beam headlights of an automotive vehicle are wired in circuit to be controlled by a pulsing rod to effect flash signals. At night a main switch is closed to illuminate both high-beam and low-beam headlights and to incorporate them in a pulsing circuit controlled by the reciprocable pulsing rod and a rocker member to flash the lights off and on by reciprocation of the rod. During the day the main switch is opened but through a branch circuit, reciprocation of the pulsing rod causes rocking of the rocker member to flash the high-beam headlight only.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
139 words
A passing signal system for automotive vehicles, which have a main headlight and a subordinate headlight, comprising an electrical power source, a movable main switch connected to said source, a second switch in circuit with said main switch and movable between first and second positions alternately to connect said main and said subordinate headlights, respectively, to said power supply only when said main switch is in a first position, a third, normally open switch interposed between said source and said main headlight and operable, when closed, to energize said main headlight from said source independently of said second switch, and means including an actuator movable in opposite directions and operative each time said actuator is moved in one direction to close said third switch and to move said second switch from one to the other of its two positions.
Claim 2
Dependent Claim
139 words
A passing signal system for automotive vehicles, which have a main headlight and a subordinate headlight, comprising an electrical power source, a movable main switch connected to said source, a second switch in circuit with said main switch and movable between first and second positions alternately to connect said main and said subordinate headlights, respectively, to said power supply only when said main switch is in a first position, a third, normally open switch interposed between said source and said main headlight and operable, when closed, to energize said main headlight from said source independently of said second switch, and means including an actuator movable in opposite directions and operative each time said actuator is moved in one direction to close said third switch and to move said second switch from one to the other of its two positions.
Claim 3
Dependent Claim
92 words
A passing signal system as defined in claim 1, wherein said means further includes a bistable control member connected to said second switch and movable between first and second positions in which it urges said second switch to its first and second positions, respectively, an electric coil in circuit with said third switch to be energized from said source each time said third switch is closed, and an armature controlled by said coil to move said control member from one to the other of its positions each time said coil is energized.
Claim 4
Dependent Claim
79 words
A passing signal system as defined in claim 1, wherein said means further includes a bistable control member connected to said second switch and movable between first and second positions in which it urges said second switch to its first and second positions, respectively, a plunger reciprocable by said actuator and operably connected to said control member to move the latter from one to the other of its two positions each time said actuator is moved in opposite directions.
Claim 5
Dependent Claim
60 words
A passing signal system as defined in claim 3, including means operative to close said third switch each time said plunger is moved a first distance in said one direction, and means operative to move said control member from one to the other of its positions each time said plunger is moved beyond said first distance in said one direction.
Claim 6
Dependent Claim
51 words
A passing signal system as defined in claim 1, wherein said main switch is connected at one side to said source and at its opposite side to said second switch, and said third switch is connected at one side to said source and at its opposite side to said main headlight.
Claim 7
Dependent Claim
38 words
A passing signal system as defined in claim 1, wherein said main switch is movable between first and second positions in each of which it connects one only of said second and third switches to said power source.
