2. BACKGROUND
The drivers of most vehicles use high bright beam while driving at night and this
may pose a great danger and inconvenience for the person travelling from the
opposite direction. Currently, in most vehicles drivers manually dim the headlight
to avoid this glare.
Therefore, this project is aimed at solving the above challenges where by an
automated headlight intensity control system is designed to detects the bright light
from the incoming vehicle and automatically dims it.

3. PROBLEM STATEMENT
The Headlight Intensity Control systems currently used in cars are manually
adjusted or operated. While travelling at night, oncoming vehicles use full light
beam intensity which deteriorates the eye sight of the driver in the approaching car.
Some drivers forget to dim their headlight intensity this results in temporary
blindness which may lead to collision of the cars causing an accident.

4. OBJECTIVES
MAIN OBJECTIVE
• To design and construct Automatic Headlight Intensity Control system.
SPECIFIC OBJECTIVES
• To design a working Headlight control circuit.
• To test the circuit performance using the software.
• To select all the required components for the system design.
• To construct the system software and hardware.
• To test and analyse the physical circuit.

5. JUSTIFICATIONS
• The project system has the ability to dim the headlights without any
human intervention, this minimizes accidents thus saving lives and
property.

6. SIGNIFICANCE
• Reduces the effect of temporal blindness.
• It also minimizes road accidents by high beam intensity.
• It is user friendly.
• It ensures safety while travelling

7. SCOPE OF THE PROJECT
• This system is specifically designed to automatically control the
headlight intensity of a vehicle once it senses the high beam intensity
of the oncoming vehicle with the help of an LDR sensor and other
circuitry.
LIMITATION
• It requires high sensitivity of the sensor component.
• Distance

12. CONCLUSION AND RECOMMENDATION
• In this project, automatic headlight intensity beam is controlled by
using LDR, Relay switch etc. The design gives the solution for night
temporary blindness which is caused by high beam headlight intensity.
so, the accidents can be reduced during night time so people can travel
safely in night time. It is very cost effective and high-performance
system.
