UN R149 — Road-illumination devices and systems
Explore headlamp, fog-lamp and adaptive-lighting functions within their own scopes.
Explore the scopeWhat does it cover?
UN R149 concerns approval of road-illumination devices and systems. It names passing- and driving-beam headlamps, adaptive front-lighting and adaptive driving beam for certain vehicles, front fog lamps and cornering lamps. The vehicle categories are not the same for every function, so identify both product type and function.
Who is it for?
Headlamp and lighting-system manufacturers, integration teams and photometric-testing specialists.
Which subjects are addressed?
- Passing and driving beams
- Adaptive lighting
- Front fog lamps
- Cornering illumination
Common question
Do all lighting functions apply to the same vehicle categories?
No. The scope specifies categories by function. Headlamps, AFS, fog lamps and cornering lamps should not be reduced to one generic category list.
