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

the Paragraphs 4.1.1. to 4.1.3. of this Annex shall comply with at least one measurement at
10m or 25m.
The measuring distance at which the test was determined shall be recorded in Paragraph 9.
of the communication form in Annex 2 of this Regulation.
The scanning is performed from downwards upwards through the cut-off line along the
vertical lines at - 2.5° and + 2.5° from the v-v Line. When so measured, the quality of the
cut-off line shall meet the following requirements:
4.1.1. Not more than one cut-off line shall be visible.
4.1.2. Sharpness of cut-off:
4.1.3. Linearity
If scanned vertically through the horizontal part of the cut-off line along vertical lines at ± 1°
from the v-v Line, the maximum value measured for the sharpness factor G of the cut-off
line shall not be less than 0.08 where:
G = (log E - log E )
The part of the cut-off line which serves vertical adjustment shall be horizontal from 3° left to
3° right of the v-v Line. This requirement is satisfied, if the vertical positions of the inflection
points according to Paragraph 3.2 above at 3° left and right of the v-v Line do not deviate by
more than ±0.20°.
