Cycles - Lighting and retro-reflective devices - Part 5: Lighting systems not powered by the cycle's movement
This document is applicable to lighting systems used on cycles intended to be used on public roads and, especially, bicycles complying with ISO 4210[1] and ISO 8098[2]. This document specifies requirements and test methods for the performance of lighting systems not powered by the cycle’s movement. It applies to lighting and light signalling devices complying with ISO 6742‑1. Lighting systems include lighting and light signalling devices and power not supplied by cycle's movement such as battery.

Overview
ISO 6742-5:2023 - "Cycles - Lighting and retro‑reflective devices - Part 5" covers performance requirements and test methods for cycle lighting systems not powered by the cycle's movement (for example, battery‑powered lamps). It applies primarily to bicycles intended for public road use and references bicycles complying with ISO 4210 and ISO 8098. The standard complements device‑level rules in ISO 6742-1 and establishes system‑level requirements for durability, water and corrosion resistance, battery indicators, marking and instructions.
Key topics and technical requirements
- Scope and system types
- Defines two system types: open systems (interoperable lamps and power sources) and closed systems (integrated, non‑interchangeable power sources).
- Corrosion resistance
- Entire lighting system shall function after salt‑spray corrosion testing per ISO 9227 (96 h, 5% salt).
- Water resistance
- Battery front and rear lights must meet IPX4 (IEC 60529) spray test; a 1 h drainage allowance is permitted after testing.
- Low battery / state‑of‑charge indicator
- Systems must include a visible low battery indicator on the lamp, battery case or display. Indicator must activate at latest when photometric requirements (ISO 6742‑1) are no longer met; lamp shall continue to emit light for at least 30 minutes after indicator activation.
- Power source safety/performance
- Batteries or power sources shall comply with applicable IEC battery standards (IEC 60086, IEC 61951‑2, IEC 61959, IEC 61960, IEC 62133) or provide equivalent performance.
- Test methods
- Specific test procedures reference ISO 6742‑1 clauses for front/rear lamps and require testing at rated or dedicated power‑source voltages.
- Instructions and marking
- Manufacturer instructions must include lamp type, compatibility warnings for closed systems, recommended batteries for open systems, charging guidance and low battery indicator function. Durable marking requirements and an abrasion/durability test are specified.
Applications - who uses this standard
- Bicycle and accessory manufacturers designing battery‑powered lamps and integrated lighting systems
- Product and electrical engineers developing compliant lighting systems (open vs closed design choices)
- Test laboratories performing conformity and type testing (salt spray, IPX4, photometric tests)
- Certification bodies, procurement teams, retailers and fleet operators validating safety and durability
- Regulators and standardization stakeholders referencing cycle lighting standards for road safety
Related standards
- ISO 6742-1:2023 (lighting & light signalling device requirements)
- ISO 6742-3:2023 (installation & instructions)
- ISO 6742-4 (lighting systems powered by cycle movement)
- ISO 4210, ISO 8098 (bicycle safety requirements)
- IEC 60529 (IP Code), ISO 9227 (salt spray), IEC battery standards (IEC 60086, IEC 62133, etc.)

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
