Proposal to Extend Parking Lamp Use for Wide Vehicles
This document presents a proposal to allow the use of single-sided parking lamp illumination for vehicles exceeding 2 meters in width. Currently, UN regulations restrict parking lamp installation on vehicles wider than 2 meters, affecting modern M1/N1 vehicles with increased widths due to safety features. The proposed amendment aims to enhance road user safety by permitting parking lamp usage for wider vehicles parked in built-up areas, aligning with evolving vehicle dimensions and safety standards.

Presence On motor vehicles not exceeding 6 m in length and not exceeding 2 m in width, optional. On all other vehicles, prohibited.
Background Information A position lamp can act as a parking lamp: 6.12.9. Other requirements The functioning of this lamp may also be performed by simultaneously switching ON the front and rear position lamps on the same side of the vehicle. In this case, lamps that meet the requirements of front or rear position lamps are deemed to meet the requirements of parking lamps.

Proposed Solution Proposed amendment to allow single side illumination of the parking lamp when a vehicle is parked in a built-up area: Parking Lamp 6.12.1. Presence On motor vehicles not exceeding 6 m in length and not exceeding 2 m in width, optional. On all other vehicles, prohibited.
Justification Modern M1/N1 vehicles have increased in width due to safety systems and for the comfort of occupants. As a result, there are now M1/N1 vehicles in the market which exceed a width of 2 m. UN R48 paragraph 6.12. does not allow parking lamps to be fitted to these vehicles. To increase the safety of road users this proposal would extend the fitment of parking lamps to vehicles which exceed 2 m in width.
