UK to EU/US Headlight Assembly inc. Parking/Side Light

Hi all,

I have a 2001 UK Forester 2.0 petrol (right-hand drive) which I am hoping to import into Europe. As such I am looking to replace the headlight assemblies with ones which point the correct way.

I found it very hard to source a pair from Europe so ended up buying some from the US. (I am aware that the beam US vs EU beam patterns differ slightly and that the certifications are also a little different - that's a different subject). I bought a pair of the right shape which were listed as being for a 2001 - 2002 Forester. All of the attachments in the right place etc. You can see these in pictures 3 & 4 which I have attached. They have a single bulb with a single 3-pin attachment in the back.

Only when I went to replace them, did I notice that my existing headlights contain two bulbs (main headlight, and what we call in the UK a side/parking light - tucked away in the corner of the assembly). On top of this there are not two but three plugs in the back - one for each bulb, and the third plug... I have no idea! Please see picture 2.

I've searched for hours and can't find any info about my assembly, let alone anywhere to buy a LHD equivalent. There's lots of single-bulb replacement assemblies available from the US, but that's it.

Is anyone able to help out? Are the parking lights being present in the assembly specific to UK / Europe? Or is it my specific model?

Cheers,
Phil
