Red is used at the rear of a vehicle to indicate braking or if the vehicles lights are switched on.
White, is obviously at the front of a vehicle.
Anything which has the potential to clash or cause confusion to a fellow road user or pedestrian, is not allowed.
So if a particularly angry FPF dissident was to smash a rear brake cluster on the 71 - apart from the member being banished to the mine shafts of Woodstone Village, that vehicle would be unroadworthy, as it is showing a white light at the rear (bulbs are generally one colour, it is the cluster that gives off the 'red' glow.
