I am taking my Focus Ghia 2001 to Europe on Weds and have a headlight conversion kit from Halfords. However I am very unclear on how to fit them! Help please!

The headlights appear to be projectors with mainly clear glass. I can see a rhumboid shaped plastic cap that shields the bulb if this makes sense.

But where do I fit the adaptors please? None of the diagrams in the leaflet seem to apply. I will be driving overnight in the UK so can't fit in advance.

Any advice would be appreciated!
