Rear fog-lights are only legal with a single light on the side of the car closest to the highway centerline (left-side rear light cluster for countries where you drive on the right side of the road, right-side rear light cluster for countries where you drive on the left side of the road). The idea is to enable vehicles approaching from the rear to be able to discern the inside corner of the car ahead of them in the fog. It's illegal (and really annoying to other drivers) to run two rear fog lights; in most jurisdictions, it's illegal to turn-on any rear fog lights in other than severe fog conditions.
