automatic headlight dimmer using ldr
The circuit described here can be built and used in your vehicle for an automatic dipping and dimming operation of the headlamps, in response to the intense lights coming from an opposite vehicle headlamps.You must have come across this irritating situation while driving at night when you find the headlight lamp focus from an opposite vehicle falling straight in your eyes, making things difficult to assess, giving rise to a situation of a collision or some kind of possible accident.Incidentally, the driver of the opposite vehicle might be going through the same situation due to the headlight focus from your vehicle.Such situations are normally tackled by using manual dipper switch mechanism, where the driver is prompted to “dip” the focus of his headlight, thus giving the opposite vehicle a chance to adjust his vehicle and also an indication that he too needs to “dip” his vehicle lamps.However, doing the above operation manually, every now and then can become horribly laborious and troublesome, therefore if some kind of automatic system is Incorporated, can help to save this headache of the driver, especially while he is driving in stressful conditions and on dangerous highways.
