REGULATION NO. 19-04
UNIFORM PROVISIONS CONCERNING THE APPROVAL OF
POWER-DRIVEN VEHICLE FRONT FOG LAMPS
INTRODUCTION
This Regulation applies to front fog lamps, which may incorporate lenses of glass or
plastic material. It incorporates two distinct classes.
The original front fog lamp, Class "B" since inception, has been updated to incorporate the
angular coordinate system with an amendment to the values in the relevant photometric
table. With this class, only light sources as specified in Regulation No. 37 are allowed.
The Class "F3" is designed to increase photometric performance. In particular the beam
width and the minimum luminous intensities below the H-H Line (Paragraph 6.4.3.of this
Regulation) have been increased whilst controls on the maximum intensity in the foreground
are introduced. Above the H-H Line, the intensity of the veiling light is reduced to improve
visibility. Additionally this class may provide adaptive beam patterns where the performance
is varied according to the visibility conditions.
The introduction of the Class "F3" provides for requirements that are amended to be similar
to those of a headlamp as follows:
(a)
The photometric values are specified as luminous intensities using the angular
coordinate system.
(b) Light sources can be selected according to the provisions of Regulation No. 37
(Incandescent filament light sources) and Regulation No. 99 (gas discharge light
sources). Light emitting diode (LED) modules may also be used.
(c)
The cut-off and the gradient definitions.
The photometric requirements permit the use of asymmetrical beam distributions.
SCOPE
This Regulation applies to front fog lamps for vehicles of Categories L , L , L , L , M, N,
and T

source control-gear shall then be switched off for a period of 10s, and be switched on again.
The light source shall restart directly after being switched-off for a period of 10s. After one
second the light source shall emit at least 80% of its objective luminous flux.

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.

Wavelengths (in nanometres) chosen are representative; other values should be
interpolated.
4.7. Temperature Stability
4.7.1. Luminous Intensity
4.7.1.1. Filament lamps and gas discharge light sources are exempted from this test.
4.7.1.2. A photometric measurement shall be made after 1min of operation with the device at room
temperature. The test point to be measured is horizontal 0° vertical 2.5° D.
4.7.1.3. The lamp shall continue operation until photometric stability has occurred. The moment at
which the photometry is stable is defined as the point in time at which the variation of the
photometric value is less than 3% within any 15min period. After stability has occurred,
aiming for complete photometry shall be performed in accordance with requirements of the
specific device. Photometry at all test points is required for the specific device.
4.7.1.4. Calculate the ratio between the photometric test point values determined in
Paragraph 4.7.1.2. and the values determined in Paragraph 4.7.1.3.above once stability of
photometry has been achieved.
4.7.1.5. Apply the ratio calculated in Paragraph 4.7.1.4. above to each of the remainder of the test
points to create a new photometric table that describes the complete photometry based on
1min of operation.
4.7.1.6. The illuminance values measured after 1min and until photometric stability has occurred,
shall comply with the minimum and maximum requirements.
4.7.2. Colour
The colour of the light emitted, measured after 1min and measured after photometric
stability has been obtained, as described in Paragraph 4.7.1.3. of this Annex, shall be within
the required colour boundaries in both instances.
