The truck tailgate position indicator is a warning system for pickup trucks that would alert the driver when the tailgate is in the lowered, or open, position. The device would consist primarily of a push button switch mounted in the truck bed such that the tailgate would push the button upon being closed, a control circuit, an indicator light, an override switch, a buzzer, and mounting hardware. When the tailgate was closed, the switch would automatically be pressed, opening the control circuit and disabling the warning light and the audible alarm. Opening the tailgate would release the switch, thereby completing the control circuit and enabling the warning system. A manual override switch would be provided to disable the warning system for those occasions when the driver wishes to travel with the tailgate in the lowered position without having a constant reminder. |
