Those illuminated fog light pics that were posted looked super cool. Does anyone remember what the rules are in the UK about when you can and cannot use them?
I have a feeling it is when visibility is less than 100m, though that sounds rather subjective to me since no one has a 100m tape measure they can stop the car and use to check, visibility tends to be variable depending on the terrain so might be 50m some places and 150 others. Also is this only for fog or mist, if its raining the visibility can easily be under 100m...?
