Title: Rear truck strobe light controller for backing or parking
Inventor: DECKARD NORMAN
IPC: B60Q1/22
Filed: 1994-05-25
Abstract: ABSTRACT OF THE DISCLOSURE    A strobe light on the back of the truck is flashed whenever the truck's transmission is either in reverse or in park, and contingent upon operation of hazard lights.  The strobe light is placed in a location on the back of the truck where other lights are not normally found, such as on a centerline of the back panel of the truck, and approximately 40-inches off the ground.  The strobe light has approximately half the brightness of a stop light and about one-third the brightness of turn signals, but it is attention getting because the light has a very sharp pulse form.  The lens of the strobe light is amber, which matches the color of a caution light on most stop and go traffic lights and on the flashing direction signals.  A control circuit for the strobe light includes a pair of switches which are operated responsive to a lighting of the clearance lights and a shifting of a transmission into either a park or a neutral position, respectively, for lighting the strobe light.  The control circuit also flashes the strobe light if the transmission is shifted into reverse.  The four-way hazard light switch is a master control for enabling the strobe light.
