equipped with suitable fixation elements.
2.2.4. The fixation elements shall be strong and firmly secured to the light source(s) and the light generator.
3. Test conditions
3.1. Application and relaxation
3.1.1. All samples shall be tested as specified in paragraph 4. below;
3.1.2. The type of light sources shall be as defined in Regulation No. 48 paragraph 2.7.1., in particular with regard to the element of visible radiation. Other types of light sources are not permitted.
3.1.3. Operating conditions
LED module or light-generator operating conditions:
3.1.3.1. All samples shall be tested under the conditions as specified in paragraph 6.4.1.4. of this Regulation.
3.1.3.2. If not specified differently in this annex, LED modules or light-generators shall be tested inside the front fog lamp as submitted by the manufacturer.
3.1.4. Ambient temperature
For the measurement of electrical and photometric characteristics, the front fog lamp shall be operated in dry and still atmosphere at an ambient temperature of 23 °C ± 5 °C.
3.1.5. In case of light-generators:
3.1.5.1. Power supply
The power supply used for the starting and run-up tests shall be sufficient to secure the quick rise of the high current pulse.
3.1.5.2. Burning position
         The burning position shall be as indicated by the applicant. Ageing and testing positions shall be identical. If the lamp is accidentally operated in the wrong direction, it shall be re-aged before measurements begin. During ageing and measurements no electrically conducting objects shall be allowed within a space as indicated by the applicant. Moreover stray magnetic fields shall be avoided.

3.2. Ageing
3.2.1. LED modules or light-generators shall be aged.
3.2.2. The tests below shall be carried out after ageing with the LED module(s) or light-generator(s) supplied by the submitted electronic light source control-gear at test voltage.
3.2.3. LED module(s)
Upon the request of the applicant the LED module shall be operated for 15 h and cooled down to ambient temperature before starting the tests as specified in this Regulation.
3.2.4. Filament lamps
Filament lamps shall first be aged at their test voltage for approximately one hour. For dual-filament lamps, each filament shall be aged separately.
3.2.5. Gas discharge light sources
With the exception of the starting test, all tests shall be carried out with light sources which have been aged for a minimum of 15 cycles having the following switching cycle: 45 minutes on, 15 seconds off, 5 minutes on, 10 minutes off.
4. Specific tests
Filament lamps approved according to Regulation No. 37, gas-discharge light sources approved according to Regulation No. 99 and LED modules are exempted from the tests indicated in paragraphs 4.3.1. and 4.3.2. below.
4.1. [Reserved]
4.2. Gas discharge light sources
The starting test shall be applied to light sources which
