Guide To: ECE Regulation 23

05 July 2018

This regulation applies to reversing lamps and other special lamps designed to aid with vehicle manoeuvring. For the purposes of regulation, a reversing lamp is classed as a light ‘designed to illuminate the road to the rear of the vehicle and to warn other road users that the vehicle is reversing or is about to reverse’.

A manoeuvring lamp means ‘a lamp used to provide supplementary illumination to the side of the vehicle to assist during slow manoeuvers’.

Each category must be tested and certified that it emits a certain level of light, either as a single or pair of lamps, to a certain colour and produces enough output over a certain vertical and horizontal plane to guarantee a minimum amount of visibility once fitted. This is to assist with manoeuvring and to ensure visibility by other road users.

For reversing lamps, the amount of light output requires varies from 600cd (candela) up to 8000cd below the accepted horizontal plane, but cannot exceed 300cd in terms of its visibility from all other angles and planes. Manoeuvring lamps can be a maximum of 500cd, but can be positioned anywhere as the user prefers and is not subject to restriction in terms of visibility from other angles and directions.

For items that indicate conformance to ECE Regulation 23, there are different markings for each category of approval as per one of the examples below. Please note that aggregated ‘E’ marks may be displayed in tabular format with either multiple categories of this regulation, or alongside other regulations (see Model B).
