INTRODUCTION

Background

Motorcycles have been the most convenient mean of transportation in Malaysia.

It has different ranges of price and quality but yet the main real fact is that motorcycles are not safe.

Motorcycle accidents represent 67 % of total accidents in Malaysia. 65 % of the motorcycle accidents happen at night

Problem Statement

• Most of the motorcycle accidents happen at night. This is due to the dim light of the motorcycle signals.

• Statistics show that for the year 2009, 2728 motorcycle accidents were recorded at night, where 1463 accidents happened during the day.

Objective

• The main objective of this project is to ensure safety on the roads. By providing a new idea for protecting motorcyclists who represent a large group of people in Malaysia and SEA.

Project DefinitionThe jacket is equipped with LED lights that are

connected to the electrical circuit of the motorbike. The back of the jacket is going to display flash lights

when the motorcyclist decides to go right or left .

Hence the safety jacket works as a visible alarm for any car driver behind the motorbike. Moreover, the

safety jacket is cheap, light in weight with an attractive design that would be suitable for all

motorcyclists from any age.

METHODOLOGY

JACKET DESIGN

• Software tools

• Microsoft Office 2010

• AutoCAD and CATIA

• Design Material

• Waterproof Clear Vinyl Fabric

• Velcro

• Polyester thread

ELECTRONIC CIRCUIT DESIGN

• Software tools

• Proteus Virtual System Modeling

• Electronic component

- LED Strip Light- Resistor 100 Ω- Blue and Red wire

- 1/ 0.5 mm Single Core Wire- Vero Board- Red and Yellow LED

ELECTRONIC CIRCUIT DESIGN – PROCEDURE

The value of component is calculated for

the best efficiency.

The schematic diagram of the

circuit is drawn.

The simulation of the circuit is

done in Proteus Virtual

System Modeling.

The components

are assembled on the circuit board based

on the schematic diagram drawn.

The components are soldered

and the component’s leg is cut for

finishing.

OVERALL JACKET DESIGN – PROCEDURE

The light signal circuitry is set

up.

The clear vinyl fabric is sewn

in form of pouch.

The light signal circuitry is

inserted into the clear vinyl pouch.

The motorcycle’s tail lamp prototype is set up as in the

schematic diagram.

The light signal circuitry is

connected to the

motorcycle’s tail lamp

prototype.The whole system is

tested and improvement

is done for any fault.
