Proposal to introduce provisions for “side-illuminating lamps” that aim to improve the driver’s visibility over the opposite side of the road (on-coming traffic side) and its buffer zone to mitigate the impact of glare from on-coming vehicles. This submission supersedes the earlier document GRE/2015/19.

This proposal concerns lamps equipped with several light sources and fitted with an operating tell-tale that indicates the failure of any one of these light sources. The current provisions for the failure of one light source (the “N-1” requirement) are difficult to apply as a complete photometric check for all possible combinations of light source failure is required. The revised text follows the approach of supplement 17 to Regulation No. 87 and removes the requirement to check the complete photometric requirement, in case of failure of any light source, when the lamp is fitted on the vehicle with an operating tell-tale.

Proposal to introduce provisions for “side-illuminating lamps” that aim to improve the driver’s visibility over the opposite side of the road (on-coming traffic side) and its buffer zone to mitigate the impact of glare from on-coming vehicles.

According to Regulation No. 119, cornering lamps that are equipped with light sources other than filament lamps, are required to meet the relevant photometric requirements after one minute and after 30 minutes of operation. However, under normal traffic conditions, these lamps are operated for no more than 6 minutes. This proposal as approved by the GRE would would require the second test after 10 minutes instead of the current 30 minutes, in accordance with standard SAE J1889.
