Scope
Governs which lighting and light-signalling devices a vehicle (categories M, N, O) must carry and, critically, where they are mounted, how they are aimed, and how they are switched and indicated to the driver. Determines what the driver sees of the road ahead (headlamp installation/levelling) and what signals other drivers perceive (position, stop, indicator, fog and conspicuity lamps). Revision 13 (December 2024) is the current consolidated text; the device-level performance sits in R148/R149/R150.
