Vehicular safety assistive device
A vehicular safety device that couples between a vehicular brake light and the vehicle's brake pedal switch, having logic responsive to each activation of the brake pedal switch to initiate an illumination pattern of a plurality of periods of various output intensity and duration of the brake light. Sequential period durations and intensities may be unequal, respectively, to their predecessors. Period durations and intensities may be uncorrelated. Sequential illumination patterns may not be identical. Illumination patterns are preferably less than five seconds long.
1. A vehicular safety device for a vehicle having a brake light and a brake switch, the vehicular safety device comprising:
a 14-stage ripple counter;
a metal-oxide field effect transistor (MOSFET) coupled to the 14-stage ripple counter;
a circuit board on which the 14-stage ripple counter and the MOSFET are mounted; and
wiring adapted to connect the circuit board to the vehicle, the wiring consisting of:
a first lead to receive power from a power source responsive to each activation of said brake switch, the first lead configured to power the 14-stage ripple counter and the MOSFET and cause the MOSFET to output an illumination pattern signal responsive to each activation of said brake switch,
a second lead adapted for connection to the brake light to energize the brake light with the illumination pattern signal, and
a third lead adapted for connection to a ground wire of the vehicle to ground the 14-stage ripple counter and the MOSFET and thereby complete an electrical circuit,
wherein the illumination pattern comprises a plurality of periods including high intensity periods between low intensity periods.
2. The vehicular safety device of claim 1 , wherein each period of said plurality of periods is more than one-tenth of a second in duration.
3. The vehicular safety device of claim 1 , wherein the high intensity periods are unequal in duration to the low intensity periods.
