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 have not been aged and have not been used for a period of at least 24 hours prior to the test. The light source shall start directly and remain alight.
4.3. Run-up
4.3.1. Filament lamps are exempted from this test.
4.3.2. Gas discharge light sources
The run-up test shall be applied to light sources which have not been used for a period of at least 1 hour prior to the test. The front fog lamp shall reach at least in the point 0°, 2.5°D on the line 6 a luminous intensity:
After 1 second: 25 per cent of its objective luminous flux;
After 4 seconds: 80 per cent of its objective luminous flux.
The objective luminous flux is indicated on the submitted data sheet.
4.4. Hot re-strike
4.4.1. Filament lamps are exempted from this test.
4.4.2. Gas discharge light sources
The light source shall be started and be operated with the electronic light source control-gear at test voltage for a period of 15 minutes. The supply voltage to the electronic light source control-gear shall then be switched off for a period of 10 seconds, and be switched on again. The light source shall restart directly after being switched-off for a period of 10 seconds. After one second the light source shall emit at least 80 per cent of its objective luminous flux.
4.5. Colour rendering
4.5.1. Red content
In addition to measurements as described in paragraph 7. of this Regulation, the minimum red content of the light of a LED module or light-generator shall be such that:
Where:
Ee () (unit: W) is the spectral distribution of the irradiance;
V() (unit: 1) is the spectral luminous efficiency;
 (unit: nm) is the wavelength.
This value shall be calculated using intervals of one nanometre.
4.6. UV-radiation
The UV-radiation of the LED module or light-generator shall be such that:
Where:
S()(unit: 1)  is the spectral weighting function;
km = 683 lm/W  is the maximum value of the luminous efficacy of radiation;
(For definitions of the other symbols see paragraph 4.5.1. above.)
This value shall be calculated using intervals of one nanometre. The UV-radiation shall be weighted according to the values as indicated in the UV table below.
