3. OBJECTIVE
 In order to avoid accidents due to temporary driver blindness, a wireless sensor network
(WSN) based controller is devised to quickly transmit sensor data between cars.
 To minimize temporary blindness headlight intensity adjustment is allowed by low
latency.
 Due to fatigue caused by repeating switching, laziness, or both, this is mostly neglected
by drivers, As a result, the headlights are left on high beam continuously, resulting in
the problems alluded.

4. INTRODUCTION
 Headlamp performance has steadily improved throughout the automobile age, spurred
by
the great disparity between daytime and nighttime traffic fatalities the US National
Highway Traffic Safety Administration states that nearly half of all traffic-related
fatalities occur in the dark, despite only 25% of traffic travelling during darkness by
these road accidents at night time increases day by day.
 Around 33% of the traffic accidents are mainly attributed to the impairment in vision
caused by the glare of impending headlights during the night travel.
 To avoid such incidents, an embedded prototype of Automatic Headlight adaptor module
is proposed.

5.  This embedded module automatically switches the high beam to low beam and
returns backs to high beam, thus reducing the sudden glareeffect.
 It also eliminates the requirement of manual switching by the driver to switch
back to low beam Automatic Headlight adaptor module is a unique solution to
achieve the above objective, the headlight intensity of the incoming vehicles
causing the glare is automatically attenuated to low beam wirelessly by the
nearby vehicles affected by high beam.

9. PROBLEM IN EXISTING SYSTEM
 In the existing systems, every vehicle
would sense the incoming headlight’s
intensity breach and regulates their own
headlight accordingly.
 So, the incoming vehicles (opposite)
would be benefited, but the high beam of
the incoming vehicle would still remain
causing temporary blindness to the
source vehicle .

universal automobile headlight control module.

10. PROBLEM IN EXISTING SYSTEM
 On receiving headlight breach and regulated their vehicle is just benefited to others we will face
glare for temporary time.
 The main problem that effected these system are, headlight intensity will change on receiving
any kind of light like street light not only vehicle light.
 These make no sense where our headlight varies its intensity on receiving every kind of light,
so to overcome these type of problems we proposed a new system using Wireless sensor
network.

11. PROPOSED EXPERIMENTAL SETUP SYSTEM
 So a newer system was thought upon which would sense the intensity of the headlights
as in the earlier system but instead of reducing their own headlight intensity with respect
to the other vehicle.
 It would reduce the intensity of the oncoming vehicle and vice versa so the problem of
temporary blindness is completely avoided.

 The function of the microcontroller in the system is to compare the intensity value of the
oncoming headlight with the threshold headlight intensity which would be set into the
system.
 The intensity obtained to the microcontroller is in the form of digital signal.

21. CONCLUSION
 The proposed embedded design system strives to remove the temporary blindness caused to
the drivers during the night vision travel. The universal embedded module automatically
switches the high beam into low beam and returns backs to high beam based on road
conditions, thus reducing the sudden glare effect.
 The interconnected modules connected wirelessly at every vehicle independently control the
headlight by evaluating various parameters like vehicle speed, current GPS location,
direction of vehicle.
