those are for the front "parking" light bulbs.
in the european version, the main lamp reflector is also used for parking-light use, using a low-wattage bulb (that is why that bulb goes through the main reflector).
This is as against the North American practice of using the indicator lights for "parking" light use, which therefore have 3 connectors each. The Euro indicator lamps on the other hand, have only 2 connectors each, although you can reuse the stock 3-connector bulb carrier with it.
i don't use the headlamp-mounted parking lights on my Euro lights, and am using the indicator lamps for this purpose, as before. This is so you can easily be seen on the side as well if you only have your parking lights on.
