ECE R.23 UNIFORM PROVISIONS CONCERNING THE APPROVAL OF REVERSING LAM PS FOR POWER-DRIVEN VEHICLES AND THEIR TRAILERS

This Regulation applies to reversing lamps for vehicles of categories M, N, O, and T1/

“Reversing lamp” means the lamp of the vehicle designed to illuminate the road to the rear of the vehicle and to warn other road users that the vehicle is reversing or about to reverse;

The definitions given in Regulation No. 48 and its series of amendments in force at the time of application for type approval shall apply to this Regul ation. The intensity of the light emitted by each of the two samples shall be not less than the minima and not greater than the maxima specified below and shall be measured in relation to the axis of reference in the directions shown below (expressed in degrees of angle with the axis of reference).

The intensity along the axis of reference shall be not less than 80 candelas.

The intensity of the light emitted in all directions in which the light can be observed shall not exceed:

300 candel as in directions in or above the horizontal plane; and, in directions below the hori zontal plane: 600 candel as between h-h and 5D and 8,000 candel as below 5°D.
In every other direction of measurement shown in Annex 3 to this Regulation, the luminous intensity shall be not less than the minima specified in that annex.

However, in the case where the reversing lamp is intended to be installed on a vehicle exclusively in a pair of devices, the photometric intensity may be verified only up to an angle of 30 inwards where a photometric value of at least 25 cd shall be satisfied.

This condition shall be clearly explained in the application for approval and relating documents.

Moreover, in the case where the type approval will be granted applying the condition above, a statement in paragraph 11. “Comments” of the communication form (see Annex 1 to this Regulation), will inform that the device shall only be installed in a pair.

In the case of a single lamp containing more than one light source, the lamp shall comply with the minimum intensity required when any one light source has failed an when all light sources are illuminated the maximum intensities shall not be exceeded.

A group of light sources, wired so that the failure of any one of them causes all of them to stop emitting light, shall be considered to be one light source.
