| Proposal to improve the visibility of direction indicators |
| Reference Number: SLR-73-08/Rev.1 |
|
Proposal to improve the visibility of direction indicators. The proposal modifies UN R48 and UN R148 requirements for direction indicator lamps grouped with stop lamps. Key changes include: requiring 75% of the rear direction indicator’s apparent surface to be more than 25mm from the stop lamp; positioning direction indicators at specified distances from the vehicle’s outer edge; and establishing a minimum apparent surface area of 30cm² for rear direction indicators. The justification cites existing installations showing inadequate visibility and references luminance studies supporting the 30cm² minimum area requirement. |
