Introduction

Safety has always been a major concern when it comes to the motorcycle riding public. Much has been attempted to present devices that would protect the rider from imminent danger, from helmets, jackets and other personal protection devices. But on the aspect of visibility, not much has been made. Riders often rely on their built in indicator and brake lights on their motorcycle to signify their intentions while going about their day to day riding activities [1].

It is for this reason that the researcher opted to develop the proposed project which is a light-weight motorcycle vest which is inexpensive to manufacture, reliable in construction, and communicates the cyclist’s intentions and actions, clearly and unambiguously to other motorists.

It is the purpose of the project to achieve the above by spacing the turn signal lights widely apart at the upper, outer edges of the back and by shaping the indicators as arrowheads pointing in the direction of the turn. Moreover, located in between the signal lights are the brake light and the tail lights. The straightforwardness of the design of the turn signal lights and the widely separated placement and the brake and tail lights thereof are not puzzling to other motorists.

The researcher was adamant in utilizing light emitting diodes since they are presently the most efficient and reliable source of luminance that can easily be integrated into most vehicles. [2]

Furthermore, the purpose of the project to ensure the proper positioning of the lights relative to the motorcycle by placing the turn signal indicators on the back of the jacket. The relative positioning of the lights do not change, for the torso of the biker seldom pivots, remaining parallel with the direction of travel by being secured by the motorist sitting on the seat while continually keeping the HANDS PRACTICALLY ON THE HANDLEBAR GRIPS.

Research Method

In this research, the Developmental Research Method was utilized which is a method that aims to systematically examine products, tools, processes, and models in order to provide reliable, usable information to both practitioners and theorists. It is intricately connected to real world practice. It creates a loop with practice informing research and research, in turn, informing practice. [3]

Type 1 developmental studies focus upon a given instructional product, program, process, or tool. They reflect an interest in identifying either general development principles or situation-specific recommendations. Typically Type 1 studies address not only product design and development, but evaluation as well. At times they may validate a particular design or development technique or tool. [4]

A standardized instrument for determining acceptability of the project was utilized. Purposive sampling was employed in determining the respondents of the study which shall consist of motorcycle riders.

Objective of the Study

The general objective of this project is to develop a motorcycle vest with indicator and brake lights for extra visibility.

Specifically, this study aims to achieve the following objectives:

  1. Design and implement a circuit capable of controlling indicator and brake lights system.
  2. Develop a method of interfacing the circuit that can be integrated into the electrical system of a motorcycle with minimal modification.
  3. Assess the acceptability of the device by possible end users.

Description of the Project

This project was designed for the Motorcycle rider’s safety and considers the comfort of the rider. The light signal on the jacket helps them to eliminate the need of using hand gestures when turning while driving and more importantly added visibility on the road.

One of the aims of the project is to power and control the tail lights, brake lights and turn signals by electrically connecting the turn signal lights to the electrical system of the motorcycle, thus allowing the jacket lights to function as an auxiliary signaling system in synchronism with the turn signal lamps fixed to the motorcycle. Use of the electrical system of the motorcycle also eliminates from the jacket per se the weight and complexity inherent in batteries, switches, flashers, and other necessary circuitry.

The project provides light emitting diodes (LEDs) as the turn signal indicators, since they are shock resistant, reliable, and of sufficient luminous output to be clearly visible to others.

It is a further object of the project to provide flat, arrow-shaped light sources as the turn signals, with the arrows pointing in the direction of the turn.

A group of evaluators composed of Motorcycle Riders, Professors and students was requested to evaluate the acceptability of the project in terms of the following criteria: (a) Functionality, (b) Reliability, (c) Usability, (d) Maintainability, (e) Workability, and (f) Safety.

Table 1: Summary of Mean scores for the Acceptability Evaluation of the Project

Criteria Mean Interpretation
Functionality 4.54 Excellent
Reliability 4.73 Excellent
Usability 4.6 Very Good
Maintainability 4.48 Very Good
Portability 4.65 Excellent
Workability 4.6 Excellent
Safety 4.53 Excellent
Overall Mean rating 4.59 Excellent

The result of the evaluation of the device resulted in a rating with a mean of 4.59, the Motorcycle Jacket with Indicator and Brake Lights proved to be acceptable in increasing safety of the motorcycle riders.

Conclusions

On the basis of the result of evaluation, the following conclusions were derived:

  1. It ensures the proper positioning of the lights relative to the motorcycle by placing the brake and indicator lights on the back of the jacket.
  2. It is powered and controlled by the brake and turn signals by electrically connecting it to the electrical system of the motorcycle. This allows the jacket lights to function as an auxiliary signaling system in synchronism with the brake & turn signal lamps fixed to the motorcycle.
  3. The system eliminates the jacket per se the weight and complexity inherent in batteries, switches, flashers and other necessary circuits.
  4. The result of the evaluation of the device resulted in a rating with a mean of 4.59, the Motorcycle Jacket with Indicator and Brake Lights proved to be very acceptable by the respondents.

Recommendations

Based on the foregoing findings and conclusions, the following recommendations were made:

  1. A better system of connecting the system with the motorcycle may be developed, wireless connectivity may also be considered.
  2. The system may be subjected to more scientific and standard methods in evaluating the capabilities of the product.
  3. The economic potential of the device may be explored by experts in the field.
