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 would therefore would require the second test after 10 minutes instead of the current 30 minutes, in accordance with standard SAE J1889.
40. The expert from GTB proposed to amend photometric stability requirements in Regulations Nos. 23 and 119 (ECE/TRANS/WP.29/GRE/2014/19, ECE/TRANS/WP.29/ GRE/2014/27). GRE adopted these proposals and requested the secretariat to submit them to WP.29 and AC.1 for consideration and vote at their March 2015 sessions as draft Supplement 20 to the original series of amendments to Regulation No. 23 and draft Supplement 4 to the 01 series of amendments to Regulation No. 119, respectively.
