Full title and description

ISO 303:2002/Cor 1:2003 — Road vehicles — Installation of lighting and light signalling devices for motor vehicles and their trailers — Technical Corrigendum 1. A short corrigendum document issued to correct, clarify or amend editorial and technical items in ISO 303:2002 related to the installation, alignment and referenced requirements for vehicle lighting and signalling devices.

Abstract

This corrigendum (Corrigendum 1) provides technical and editorial corrections to ISO 303:2002. It is a two‑page corrigendum that updates/clarifies specific clauses, figures or normative references in the 2002 edition of ISO 303 dealing with the installation and setting of lighting and light‑signalling devices on road vehicles and their trailers. The corrigendum itself has been withdrawn; users should consult current national regulations or later ISO deliverables for up‑to‑date requirements.

Scope

This corrigendum applies to ISO 303:2002 and is limited in scope to correcting, clarifying or amending specific text, figures or normative references within that standard. ISO 303:2002 sets out essential characteristics and installation requirements for lighting and light signalling devices on motor vehicles (four wheels or more) and their trailers; the corrigendum does not introduce a new technical regime but adjusts the published 2002 text where errors or ambiguities were identified.

Key topics and requirements

• Editorial and technical corrections to ISO 303:2002 wording and tables.
• Clarifications on mounting, adjustment and orientation of lamps and signalling devices when fitted to vehicles.
• Corrections to figures, dimensions or angle references affecting geometric visibility and alignment checks.
• Updates to normative references or cross‑references within the 2002 text.
• Notes to ensure correct application where national or UNECE regulatory requirements overlap.

Typical use and users

Used by vehicle manufacturers, lighting-system designers and suppliers, type‑approval and homologation authorities, testing laboratories, standards developers and regulatory bodies as a short corrective document to the ISO 303:2002 text. Because the corrigendum is withdrawn, these stakeholders should verify the current normative requirements with national regulations or later ISO/UNECE documents before applying it.

Related standards

FAQ

Q: What is this standard?

A: ISO 303:2002/Cor 1:2003 is a technical corrigendum (Corrigendum 1) to ISO 303:2002, issued to correct or clarify parts of the 2002 edition that cover installation of lighting and light signalling devices on motor vehicles and trailers.

Q: What does it cover?

A: It provides limited corrections and editorial clarifications to the main ISO 303:2002 document—items such as wording, figures, dimensions, alignment instructions and normative references that required amendment after publication of the 2002 edition.

Q: Who typically uses it?

A: Vehicle manufacturers, component suppliers, test and certification bodies, regulatory authorities and standards committees involved in vehicle lighting, installation and type‑approval processes.

Q: Is it current or superseded?

A: The corrigendum was published in August 2003 and is recorded as withdrawn. The parent standard ISO 303:2002 and its corrigendum have been withdrawn; users should check the latest ISO publications and applicable national/UNECE regulations for current requirements. (The corrigendum document itself is a short correction and does not replace the main standard.)

Q: Is it part of a series?

A: Yes. ISO 303 has prior and related editions (for example ISO 303:1986 and ISO 303:2002). The work falls under ISO/TC 22 (Road vehicles) and links to other vehicle‑lighting standards and sector‑specific ISO documents.

Q: What are the key keywords?

A: Vehicle lighting, light signalling, installation, lamp alignment, ISO 303, corrigendum, road vehicles, trailers, type‑approval.
