Introduction
The visibility of agricultural vehicles is of great importance for road safety.
Lighting and light-signalling devices such as lights, light-signalling devices, reflectors, conspicuity
markings, signalling foils, etc. are used for this purpose. Their number and kind of installation to mounted
implements is usually regulated in the respective national road traffic regulations.
Whereas there is an EU type-approval procedure for agricultural tractors, trailers and towed
interchangeable equipment with corresponding harmonized requirements, there is no harmonized set of
regulations for mounted implements. Mounted implements are also not covered by the relevant
UN Regulation No 86 because they are not vehicles, systems, components and separate technical units
within the meaning of UN/WP.29 Resolution R.E.3.
The respective national regulations for the lighting and marking of mounted implements are very similar
within the EU Member States, but nevertheless differ slightly in detail.
For these reasons, this document is intended to provide a basis for a uniform approach to the installation
of lighting and light-signalling devices to mounted implements. It has been prepared on the basis of the
requirements of UN Regulation No 86, as these requirements cannot be applied directly to mounted
implements for formal reasons.

1 Scope
This document applies to front and rear-mounted implements on agricultural or forestry tractors, self-
propelled machines, trailers or on towed machinery.
This document specifies the requirements for lighting and light-signalling devices to be installed on the
implement for safe on-road use.
NOTE Mounted implements are considered to be interchangeable equipment and become part of the tractor,
self-propelled machine, trailer or towed machine to which they are attached.
This document describes the installation of lighting and light signalling devices on mounted implements
when the vehicle's lighting and signalling devices cannot comply with the applicable road regulation
requirements.
