Which marking indicates that a lamp is type approved?

  • A.An E mark with a country number in a circle
  • B.A CE mark, which indicates conformity with the applicable directives and is required on every automotive lamp
  • C.A wattage figure
  • D.An approval number moulded into the lens, which identifies the standard against which the lamp has been tested

Answer: A

The circled E and the approval number identify the approving authority and the standard. The approval number genuinely accompanies the E mark, which makes the last option a correct description of part of the same marking. The shared behaviour explains why these belong together and the differences explain why both exist. Tracing the requirement back to the physical constraint that produces it makes the answer follow.
