ECE regulations define cross-border technical regulations for establishing approval or uniform approval procedures for motor vehicles and motor vehicle parts. Automated commercial vehicles are already fully eligible for approval only through appropriate individual measures in the country in which they will be used. What is missing is a set of rules at the international ECE level.
Regulation 149 of the United Nations Economic Commission for Europe (UN/ECE) — Covers the uniform provisions regarding the approval of road lighting devices (lamps) and systems for powered vehicles and the tests applied accordingly.
ECE R149 Regulation applies to the following road lighting devices:
1)Headlights emitting high beam and/or asymmetrical low beam for vehicles of category L, M, N and T
2)Adaptive front lighting systems (AFS) for M and N category vehicles
3)Headlights emitting high beam and/or symmetrical low beam for vehicles of category L and T
4)Front fog lamps for vehicles of categories L 3 , L 4 , L 5 , L 7 , M, N and T
5)cornering lights for vehicles of category M, N and T
Lamps must be designed and constructed in such a way that they are guaranteed to operate satisfactorily under normal conditions of use and regardless of the vibrations to which they may be subjected, and to maintain the characteristics set forth in this Regulation.
Lamps should be constructed in such a way as to provide adequate illumination without glare when sending the low beam and good illumination when sending the high beam. Twist lighting can be produced by activating an additional filament light source, one or more additional LED light source(s), or one or more additional LED modules that are part of a lamp that produces a passing beam.
When there is a lamp producing a main low beam and a lamp producing a high beam, each equipped with its own light source(s) or LED module(s), the setting device must activate the main low beam and high beam.
