Correct answer
One or two, red in colour.
A passenger car must have one or two red rear fog lights. A single lamp may be central or on the left; with two, one is fitted on each side. Switch them on only when weather or environmental conditions are especially unfavourable, such as thick fog, very heavy rain, heavy snowfall or dense clouds of dust or smoke.
