High Beam H15, in Lower Part Reflector Feasibility study Low Beam H7 TL909 is fulfilled Golf A6 fulfilled ECE : R112B is fulfilled USA : FMVSS108 could be fulfilled. High Beam H15, in Lower Part Reflector Golf A6 is fulfilled USA : FMVSS108 could be fulfilled (by decreasing the maximum value Emax≤100lx and by increasing the width of the beam), at the limit because of the low interior vehicle angle (18.3º) DRL H15, optical surfaces in Upper Part Reflector ECE : R87 is not fulfilled USA + Canada : CMVSS108 is fulfilled without margin I 3

Lighting feasibility study HB-DRL – Analysis of Dimensions

Lighting feasibility study Low Beam – With all geometry – Lens Loss estimated LB H7 (12V) - Left Side Flux : 541 lm Maxi : 45.4 lx ECE – R112B LB The distribution is not cut by the geometry I 7

Lighting feasibility study High Beam – With all geometry – Lens Loss estimated HB H15 (13.2V) - Left Side Flux : 543 lm Maxi : 119 lx ECE – R112B HB I 8

Lighting feasibility study High Beam – With all geometry – Lens Loss estimated HB H15 (12.0V) - Left Side Flux : 402 lm Maxi : 88 lx ECE – R112B HB I 9

Lighting feasibility study Comparison basis version with current Golf Low Beam H7 – Left Hand Current Golf Golf A7 Flux 552 lm 541 lm Max Value 54 lx 45.4 lx Width of the beam (0.4 lx) -33º to 18º -32º to 20º High Beam – Left Hand Current Golf Golf A7 Flux 560 lm 543 lm Max Value 110 lx 119 lx Width of the beam (0.4 lx) -16º to +16º -18º to +18º Recommendations to get the better performances : LOW BEAM Maximum: it is not a problem, it will be adjusted in serial definition to achieved the reference. HIGH BEAM To adjust the definition, reducing the maximum according USA regulation requirements To improve the width of the beam : increasing the interior output angle to reach a value of 20º Reference flux is almost achieved: increase output.

Signalling feasibility study DRL H15 (290 lm @ 13.5V) - Left Side – Simulation with all geometry ECE regulation : KO, Maxi over 1200cd (due to the wall). No margin USA + CANADA : OK without margin Flux : 102 lm ECE – R87 USA/Canada – CMVSS108 Not enough output at inside vehicle for the DRL (lens) Maxi > 1200 Cd due to the wall : the wall must include stripes and/or change inclination I 11

Signalling feasibility study DRL H15 (198 lm @ 12V – No homologation voltage) - Left Side – Simulation with all geometry ECE regulation :KO USA + CANADA : KO Flux : 68 lm ECE – R87 USA/Canada – CMVSS108 I 12

Conclusions Lighting: Signaling: OK Output inside angle must be increased in order to fulfill DRL regulations for USA-CANADA. Wall must include stripes or change its inclination to avoid spots over the regulation. I 13
