Car Head Lights Turn Off

This circuit when setup in a car automatically turns off the head light after a preset time after the ignition switch is turned off.So you can walk out easily from the dark garage in the light of your car.

Car Head Lights Turn Off  Circuit Diagram

When the ignition switched on first the voltage from battery is fed to the relay through diode D1.When the ignition switch is turned off it produces a negative going pulse at the pin 2 that triggers the timer. The output of the IC goes high for the time set by R1  .This makes the transistor Q1 to conduct to energize the relay to drive the headlight.After the set time the light goes off.With the value of components used you can make a setting from 10 S to 60 S.
Notes :

• Assemble the circuit on a good quality PCB or common board.
• Fit the potentiometer on somewhere on the dashboard so that  you can easily set the timing.

LA47536 bassed high power car audio amplifier circuit with explanation

This car audio amplifier circuit is based on LA47536 audio amplifier integrated circuit designed by Sanyo . This audio amplifier circuit is specially designed for car audio power amplifiers and . LA47536 car audio amplifier IC has four output channels and is capable to provide a maximum output power of 45 watts on each channel on a 4 ohms load with 10% THD .
The LA47536 includes almost all the functions required for car audio use, including a standby switch, muting function, and various protections (output pin-to-VCC short , output pin-to-GND short ,load short , over voltage , thermal shut down circuit ). It also provides a self-diagnosis function (output offset detection).

Also this audio amplifier IC has a voltage gain of 32 dB and a self-diagnosis function that detects the output offset . For powering this car audio amplifier circuit you will need a 14. 4 volts DC , or you can use the car battery ( if you will use it for car ) .
Using a 12 volts Dc power supply , the output power will be a little low , but the distortion ( THD ) will be very low .
