Description (English):

This document specifies requirements for installation and performance of lighting, signalling and marking lights, and reflex reflectors. It is applicable to ride-on self-propelled wheeled or crawler earth-moving machines as defined in ISO 6165, and rough-terrain variable-reach trucks as defined in ISO 10896-1 and ISO 10896-2, hereafter known as “machines”. These machines are used off-road and can occasionally be driven on the road. NOTE 1 Meeting the requirements of this document does not ensure conformance to national or regional on-road regulations. NOTE 2 Rough-terrain trucks with mast as defined in ISO 3691-1 and rough-terrain lorry-mounted trucks as defined in ISO 20297-1 are not specifically covered by this document, but this document can be used for guidance.

Abstract

Overview - ISO 12509:2023 (Earth-moving machinery lighting, signalling and marking)

ISO 12509:2023 specifies requirements for the installation and performance of lighting, signalling and marking lights, and reflex reflectors on off‑road machines. It applies to ride‑on self‑propelled wheeled or crawler earth‑moving machines (see ISO 6165) and rough‑terrain variable‑reach trucks (see ISO 10896‑1 and ISO 10896‑2). The third edition (2023) updates definitions, normative references and technical clauses from the previous edition. Note that conformity to ISO 12509:2023 does not guarantee compliance with national or regional on‑road vehicle regulations.

Key topics and technical requirements

Scope and applicability: Off‑road earth‑moving machines and rough‑terrain trucks; guidance for certain truck types not specifically covered (e.g., mast or lorry‑mounted variants).
Installation requirements: Principles for mounting lamps, marking lights and reflex reflectors to ensure visibility and durability in earth‑moving environments.
Performance and photometry: Requirements for light output, colour, geometric visibility and reference axes for photometric measurements.
Terms, definitions and symbols: Standardized vocabulary (reference axes, light‑emitting surface, reference centre, ground reference plane) to support consistent testing and installation.
Data sheets and documentation: Annex C (normative) defines data sheet formats for lighting, signalling and marking devices to document performance and mounting data.
Lighting combinations and configurations: Annex A normative guidance on acceptable lamp combinations for different machine uses.
Visibility guidance: Annex B informative material on forward visibility of red light and rearward visibility of white light; Annex D provides location guidance.
Safety signals: Requirements and guidance for emergency braking signals and tell‑tales (see Annex F/D).
Normative references: Links to ISO 6165, ISO 10896‑1/2 and related standards governing machine types and safety verification.

Practical applications - who uses ISO 12509:2023

Machine manufacturers and OEMs designing lighting and signalling systems for earth‑moving machinery and rough‑terrain trucks.
Component suppliers and lamp manufacturers preparing product data sheets and conformity evidence.
Safety engineers, compliance officers and test laboratories performing installation checks and photometric testing.
Fleet operators and maintenance teams implementing retrofits or replacements to improve visibility and workplace safety.

Related standards and notes

Related: ISO 6165, ISO 10896‑1, ISO 10896‑2 (machine definitions and safety requirements).
Reminder: ISO 12509:2023 provides off‑road lighting/marking requirements but does not substitute national on‑road lighting regulations. Consult local vehicle standards and ISO for full text and purchase.
