Source: InternetPublisher:三月小雨 Keywords: Alarm car headlights Updated: 2024/05/24
This is the circuit diagram of a car headlight alarm. The device can be set to one or two functions:
One is to indicate that the headlights (or sidelights) should be turned off after the ignition contacts are closed. With this circuit, you should never have a dead battery with the headlights on.
Secondly, indicate that once the ignition contacts are connected, the headlights should come on.
Components List:
Car headlight alarm function:
Continuous repeating alarm tone when light is on (may be disabled)
Repeating alarm tone of light OUT
