The document presents a prototype for a steerable headlight system designed to enhance nighttime visibility and safety on curved roads. It includes an adaptive lighting system that modifies conventional headlamps using various components like potentiometers, microcontrollers, and servomotors. Future improvements could add functions for conditions like rain and fog, while it acknowledges limitations in design and regulations.

2. INTRODUCTION
• The highest fatal traffic accident rate occurs on
curved roads at nighttime due to the late recognition
of objects in the traffic zone.
• The static headlamp just provides certain illuminating
fields for drivers in the nighttime and is insufficient to
serve on curved roads
• In order to provide enhanced nighttime safety
measures this work aims to design and build a
prototype of steerable headlights by adapting a
conventional static headlamp.

3. OBJECTIVE
• To design and build an Adaptive Front
Lightening System prototype that will modify an
existing fixed headlamp with a very close eye on
cost and reliability.
• To improve adequate visibility at the curved
path.
• To improve driver’s comfort at night time.
• Change the vehicle’s condition static to dynamic.
• To increase road and pedestrian safety.

4. COMPONENTS
• STEERING SYSTEM
• SENSOR BLOCK
– Potentiometer
– Analog-Digital Convertor
• MICROCONTROLLER
• ACTUATOR BLOCK
– Servomotor
– Headlamps and Headlamp Casing

HEADLAMPS
SERVOMOTOR

6. STEERING SYSTEM
• Steering system is used to convert rotary movement of
steering wheel into angular turn of the front wheels.
• As the steering shaft rotates(taking corners), it will turn
the axle of potentiometer & therefore vary the voltage
input.

7. POTENTIOMETER
• Due to rotation of the shaft of potentiometer it supplies
variable voltage to microcontroller.

8. MICROCONTROLLER
Voltage output from
potentiometer
A/D converter
Read value from the
potentiometer
Feedback
Manipulate value into pulse
length
Output to the servomotor

9. SERVOMOTOR
• It is a type of motor which
rotates in both the clockwise
and
counter
clockwise
directions.
• It consists of 3 wires: red,
black, and blue. The red and
black are the positive and
negative power supplies,
whereas the blue is for
signaling.

10. HEADLAMPS
• Headlamps are mounted
on servomotor.
• The casing of headlamps is
made light in weight as
much possible (such as
Aluminum metal) to rotate
it effectively.

11. ADVANTAGES
• Better visibility and identification of obstacles
on curved path
• Improved Comfort
• Ease of handling
• Components are available easily in market

12. FUTURE SCOPE
• In future we can add more functions to an
adaptive front light system such as to increase
the intensity of light of front headlamps in
rain, fog etc..
• Functions can be made rather simple but still
effective in there basic version and will
probably easy to sell because they are not very
well covered by the traditional vehicle
illumination system.

13. LIMITATIONS
• Economical and Technical Limitations
• Designing limitation such as space provided to
rotate the Headlamps
• International differences in regulations on
what the designer could and couldn’t do
• Can’t tell about customer reviews
• Lack of innovation
