Patent number: 5811888Abstract: An automatic vehicle power and headlight controlling device with delay effect, including a delay circuit, an in-car sensing circuit, an out-car sensing circuit and a power supply circuit. The delay circuit is connected to both the in-car sensing circuit and the power supply circuit, while the out-car sensing circuit is connected to the in-car sensing circuit and powered thereby. After the delay circuit works, the in-car sensing circuit and the power supply circuit are delayedly energized. Only when the in-car sensing circuit works, the out-car sensing circuit is energized. Accordingly, at the stage of initially starting the vehicle, the excessive load on the battery is avoided so that the damage of the battery resulting from the excessive load can be obviated.Type: GrantFiled: November 12, 1996Date of Patent: September 22, 1998Inventor: Cheng-Tien Hsieh
