Implementation of the lighting test for the homologation of motorcycles and tricycles according to the ISO 11460:2007 standard
1. INTRODUCTION
The purpose of this work is to know about the
international standard ISO 11460:2007 and its
assessment of motorcycles and tricycles in Quito
[1]. This is specically related to determine the
kind of illumination devices in these vehicles. The
conguration and intensity of headlights play a
crucial role in the prevention of trac accidents,
both in four-wheeled vehicles and on motorcycles
and tricycles. It is recognized that low headlight
intensity can prevent a driver approaching an
intersection from detecting the presence of another
vehicle, which could lead to accidents, especially
in areas without trac lights or signaling [2]. On
the other hand, excessively high intensity can make
it dicult for oncoming drivers to see. In relation
to this issue, the National Trac Agency (ANT)
reports that, until April 2021, of all accidents
registered in Ecuador, 33 are linked to various
mechanical problems, of which 29 are related to
the lighting and design of the devices, representing
0.4% of the total. Therefore, the primary objective
of this study was to conduct lighting tests for the
certication of motorcycles and tricycles in Quito.
To conduct these tests, ve motorcycles from the
2019 and latest, both domestically assembled and
imported, were selected as a sample. The study
related to this international standard is detailed in an
evaluation test report, which will demonstrate the
deciencies and compliance levels observed in the
motorcycles that make up the study sample.
The results will determine the current state of this
study’s issue [3], [4]. This study is divided into
three parts:
The rst part deals with the origins and the signicance
of motorcycle lighting systems. The second part
analyzes how these systems impact the performance
of motorcycles. Finally, it provides a detailed
examination of the application of lighting systems and
their advantages from previous studies [5].
In conclusion, the study presents the following
research objectives:
Interpret the parameters in accordance with the
required regulations for conducting lighting tests
on motorcycles and tricycles, following ISO
11460:2007.
Implement the devices used in the lighting tests.
Analyze various cases and research on lighting
systems and their use in the automotive eld,
focusing on dierent components of a motorcycle.
This research will focus on analyzing the degree of
compliance with the aforementioned requirement
according to ISO 11460 of the International
Organization for Standardization. It is important to
note that there is neither a specic regulatory body
for this standard nor established tools to measure its
application.

It is a critical component of any motorcycle. Each
light on a motorcycle serves a specic function, and
its location, size, and color depend on its intended
purpose. According to the regulations [7], the basic
requirements that must be considered include:
Headlight: Position and orientation. It can be
separate from the front light and may be installed
above, below, or to the sides of the front light, with
reference centers being symmetric with respect to
the longitudinal plane of the vehicle [8]. The lights
should be oriented forward.
Dipped Beam Light: Position and orientation.
It can be separate or reciprocal to the front light,
with installation above, below, or on each side of
the front light. If there are two dipped beam lights,
they must be incorporated in such a way that they
are symmetrical with respect to the vehicle’s
longitudinal plane. Their height should not be less
than 500 mm or more than 1200 mm from the
ground. The lights must be oriented forward.
Front Position Light: Position and orientation. Like
the previous lights, it can be separate or combined
with another front light. The height of the light with
respect to the ground should not be less than 350
mm or more than 1200 mm. The headlight beams
are oriented forward.
Side Retroreective Device: Position and orientation.
There are no specic width requirements, but its
height should not be less than 300 mm or more than
900 mm from the ground. The orientation should be
perpendicular to the vehicle’s median longitudinal
plane and outward.
Rear Retroreective Device: Position and
orientation. Its reference center should be oriented
to the vehicle’s median longitudinal plane. The
reference center should be symmetrical concerning
