Basic 12V Automotive Headlights And Indicators

Automobiles have several signalling devices such as indicators, brake lights, hazard warning lights, headlights and reversing lights. This circuit demonstrates these signalling devices using basic components. Please note a transistor is usually connected to pin 3 of the 555 timer chip. * The SPST switch located below the headlight lamps controls the headlights plus the front and rear parking lamps. * The SPST switch located next to the headlight SPST switch contols the headlight high beam (two additional lamps) * The SPST switch located next to the 555 timer controls the reverse lights. * The two SPST switches connected next to each other controls the left and right front and rear indicators. * The SPST switch located in the middle of the indicator SPST switches controls the hazard warning lights. * The push button located on the top left side of the 555 timer controls the brake lights. * The SPST switch located on the left side of the 555 timer is the battery isolation switch.
