Automatic headlight Switch Dim.
The administrator may-1-200818 COMMENTS
Description.
In this cool integrated circuit to your auto headlight system, you can ride in the high beam.The cool chain headed will assume the duty of passing lamp shining against when vehicles approach lights and high beams when they pass over.
The chart is based on the photo transistor (Q1) to measure the oncoming vehicles and transistor Q2 (BC177) to switch the relay to control headlight.When the light from the opposite vehicle falls on Q2, the collector current of Q1 a ....etc

Project is based on the vanet created using zigbee. Vehicles mostly drive at high beam during night time which is uncomfortable for the car coming from opposite lane to pass away. Therefore we have introduced a device in which rather than switching the headlight to low beam, it automatically turns to low beam. The working is as follows.
Two circuits are made. Every circuit consists of a zigbee, an 89c51 atmega microcontroller, Max 232 IC, relay circuit and timmer ic's for connection to the headlight, RS 232 serial port. The zigbee creates a ve ....etc

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 ....etc

steering controlled headlight ppt

ABSTRACT

The topic of this project is steering controlled (or directional) headlights, that are usually a separate set of headlights fitted to road vehicles beside the usual low beam/high beam headlights and their feature is that they turn with the steering, so that the driver of the vehicle can see the bend, what he is actually turning into. These type of headlights appeared on production cars in the 1920 s and are still around nowadays, but not very popular, although they make night time driving safer. T ....etc

ABSTRACT
The number of vehicles on our roads is burgeoning day by day. This is turn forced almost all this vehicle manufactures to think about the extra safety instruments and electronic controls to attach with these products for giving the users a safety derived in all road conditions through a mass flow traffic. If asked, one should always mention that the right driving is very cumbersome due to the dazzling light problems and the frequent dipping of headlights by manual means that often causes fatigue ....etc

steering controlled headlight ppt free download

ABSTRACT:

Special safety features have been built into cars for years, some for the safety of car s occupants only, and some for the safety of others. One of the choices available is Design and fabrication of steering controlled head light system. Car safety is the avoidance of automobile accidents or the minimization of harmful effects of accidents, in particular as pertaining to human life and health. Still, more specially, this device relates to a headlight arrangement operably connected to ....etc

While driving a car in night a problem like many drivers do not dip the head lamps of their vehicles in night while approaching. The several switching operation is used to dip the head light which may distract the concentration. To overcome this type of problem the innovative group Dreamlover Technology designs a unique electronics gadget called Automatic Dipper using very popular IC NE555 and LDR.
Circuit Description
The entire circuit of automatic dipper consist LDR followed by timer IC NE555 (IC1) and few other components, where LDR is u ....etc
