SO missing UK fog lights when driving here in NJ.

First really foggy morning of the autumn here last week and drivers are obviously conscious of the lack of visibility, because they're driving with their hazard lights on.
Unfortunately, the Hazards conflict with brake lights, and I couldn't tell when the guy in front was actually braking.
The benefit of a single rear fog light is that it improves visibility from a distance, until you get closer and can see normal tail lights. Yes, many people leave them on in the UK, but soon learn when they realise they're continually getting flashed by other drivers from the rear.
I'll be fitting the Euro switch ASAP.
