It's ambiguous. I still infer that it means separate reflector and light. Just had a look at my rear light (a Spanninga) There is no reference to BS at all. Nor can I find any "EC equivalent standard on Google."Rear Lamp
One is required, to show a red light, positioned centrally or offside, between 350mm and 1500mm from the ground, at or near the rear, aligned towards and visible from behind. If capable of emitting a steady light it must be marked as conforming to BS3648, or BS6102/3, or an equivalent EC standard.
If capable of emitting only a flashing light, it must emit at least 4 candela.
Rear Reflector
One is required, coloured red, marked BS6102/2 (or equivalent), positioned centrally or offside, between 250mm and 900mm from the ground, at or near the rear, aligned towards and visible from behind.
by my reading, if its between 350 and 900mm from the ground, the combined one is legal if marked appropriately "

Here is this mornings test. What do the following Spanninga markings mean?
