4 Lamps and interchangeable power source
4.1 General
The complete system shall be designed as closed system which does not have compatibility between lamps and power source.
4.2 Requirement
When tested by the method described in 7.1 and 7.3, lamps with interchangeable power source shall correspond with the requirements of Clause 6 and ISO 6742-1:2015, Clause 4.
5 Lamps and dedicated power source
5.1 General
The complete system shall be designed as open system which requires compatibility between lamps and power source.
5.2 Requirements
When tested by the method described in 7.2 and 7.3, lamps with dedicated power source shall correspond with the requirements of Clause 6 and ISO 6742-1:2015, Clause 4.
6 Common requirements for lighting systems
6.1 Corrosion resistance
The lighting equipment shall still be functional after testing has taken place.
6.2 Water resistance
The lighting equipment shall still be functional after testing has taken place.
6.3 Low battery indicator
The lighting system shall include a low battery indicator or state of charge indicator. This indicator shall be located on the lamp, on the battery case or on display, clearly and easily visible.
The indicator shall be activated at the latest when the photometrical requirements of ISO 6742-1 are not fulfilled anymore. The lamp shall emit light for at least 30 min after activation of the indicator.
6.4 Power source
Battery or any kind of power source shall comply with the requirement of IEC 60086, IEC 61960, and IEC 62133 if applicable.
7 Test method
7.1 Lamps and interchangeable power source
7.1.1 Lamps emitting light to the front Lamps have to be tested corresponding with the test methods of ISO 6742-1:2015, 4.2 (Front position lamp), 4.5 (Low beam), 4.6 (High beam) and 4.7 (Direction indicators). The test voltage shall be the rated voltage of power source.
7.1.2 Lamps emitting light to the rear Rear lights have to be tested corresponding with the test methods of ISO 6742-1:2015, 4.3 (Rear lamp), 4.4 (Stop lamp), 4.7 (Direction indicators) and 4.8 (Stand light). The test voltage shall be the rated voltage of power source.
7.2 Lamps and dedicated power source 7.2.1 Lamps emitting light to the front Lamps have to be tested corresponding with the test methods of ISO 6742-1:2015, 4.2 (Front position lamp), 4.5 (Low beam), 4.6 (High beam) and 4.7 (Direction indicators). The test voltage shall be the rated voltage of power source or dedicated power source. 7.2.2 Lamps emitting light to the rear Rear lights have to be tested corresponding with the test methods of ISO 6742-1:2015, 4.3 (Rear lamp), 4.4 (Stop lamp), 4.7 (Direction indicators) and 4.8 (Stand light). The test voltage shall be the rated voltage of power source or dedicated power source.
7.3 Common test methods for lighting systems
7.3.1 Corrosion testing The entire lighting system (front lights, rear lights in functional assembly conditions) shall undergo corrosion testing according to ISO 9227. A total of 96 h shall be run with a salt concentration of 5 %.
7.3.2 Water resistance Battery rear lights in functional assembly conditions shall undergo water spray testing according to IEC 60529, regarding class IPX4: protection against water sprays. Battery front lights shall fulfil the class IPX4. At the end of the test allow the unit to drain for 1 h.
8 Instructions
The instructions shall be provided with lighting devices. These instructions can be provided in all type of format (paper, CD, website…) according to national regulations and shall be written in the language of the country where the lighting device is to be marketed or by visual tools, such as pictograms and illustrations shall feature prominently in the product safety information. When an electronic format is provided, a paper version shall be available upon request. The customer shall be made aware of this information either by the manufacturer or the retailer. Instructions for use shall contain the following information on:
a) type of lamp;
