a ≥ 8mm The headlamp bearing one of the above approval marks has been approved in the Netherlands (E 4) pursuant to Regulation No 112 under approval number 243, meeting the requirements of this Regulation in its original form (00). The passing beam is designed for right-hand traffic only. The letters CR (Figure 1) indicate that it concerns a Class A passing and driving beam and the letters HCR (Figure 2) indicate that it concerns a Class B passing and driving beam. The figure 30 indicates that the maximum luminous intensity of the driving beam is between 86 250 and 101 250 candelas.
The use of roman numerals as approval numbers should be avoided so as to prevent any confusion with other symbols. |
