Abstract

A system for implementing strobing of existing vehicle hazard lights including an interface to a vehicle wiring harness configured to receive input to an existing vehicle flasher module, a strobing circuit that responds to an activation signal from the vehicle wiring harness that is indicative of a hazard flasher deployment event by producing an electrical output having a strobing pattern that is perceptibly faster than a cycle of existing vehicle signal lights, and an OR circuit having two inputs, one of which accepts the electrical output from the strobing circuit and another of which intercepts output to an existing auxiliary vehicle lamp that is not otherwise activated with existing vehicle flashers or signal lights.
