2. 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 indicater
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 the steering and front wheel assembly of and automobile operably to maintain
headlight members and the front wheels pointed in the same direction at all times.

3. INTRODUCTION
Present day automobiles don’t have effective lighting system. Due to this many accidents are taking place during
night times especially in ghat sections. Conventional indicater lights tend to illuminate the side of the road while
cornering or shine off the road entirely, which can lead to unsafe condition. To overcome this problem an idea has been
developed by introducing “Steering Controlled indicater lights Mechanism”. Steering Controlled indicater light
Mechanism includes Headlights, Steering System which are interconnected by using cables. The actual Steering
Controlled Headlight Mechanism is the indicaterlights follow the motion of front wheels.

5. WORKING PRINCIPLE
This is done by connecting indicaterlights and steering. Present day automobiles don’t have effective lighting
system. Due to this many accidents are taking place during night times especially in ghat sections. The accidents can
be avoided by incorporating Steering Control indicaterlight Mechanism.
The rack and pinion steering gear mechanism is used for this project. When the steering wheel is rotated and
rotary motion is converted to translator motion through the rack and pinion mechanism.
When the front wheels are steered, the headlights follows the same path and the light is focused on more
divergent area. In the present project, it is planned to design “Steering Controlled indicaterlight Mechanism” and a live
model unit is fabricated.

7. Applications
The steering controlled indicater light mechanism can be applied in heavy vehicles such as buses, trucks, which ride
maximum in the ghat roads.
Specially designed for installing in buses riding in ghat roads.
This mechanism can also install in all types of commercial vehicles such as:
❖ Maruthi,
❖ Ambassador,
❖ Fiat,
❖ Mahindra,
❖ Tata, etc.,

8. CONCLUSION
An effective steering controlled indicaterlight mechanism was designed, based on Ackermann Steering
mechanism and a live model was developed.
Cost analysis was also done and a new mechanism at nominal cost was presented
