In-Car lights delay circuit

Hosted circuit

 



This circuit switch slowly on and off the internal lights in a car. The delaying time can be adjusted changing the values of the 10k, 4M7 resistors and capacitor.
In-Car lights delay circuit

The BUZ74 can handle voltages of 500V, but you can use any power Mosfet transistor that can handle more than 50V.
