Are those dual rear fogs OEM?
I don't believe so, there should be only one in the rear, based on what I've seen, read and a little common sense.
JDM lights/cars do not have fog lights, it's standard euro equipment.
Countries where they require rear fog lights and have RHD vehicles/drive on the left side of the road, the fog light will be on the right side and LHD countries will have the fog light on the left.
Purpose being to help with visibility in inclement/poor conditions to let you know there is a vehicle in front of you, and know their road position.
