They mark the edge of the safe area, keep clear of them. In the UK red reflectors are always shown to the rear of a vehicle, never to the front, therefore they mean you are approaching the rear of car, lorry, bike etc.
Rear reflectors are red primarily because red light is associated with warning and caution, making them highly visible to drivers approaching from behind. This color choice helps signal to other road users that a vehicle is present and may be stationary or moving slowly. Additionally, red light is less likely to cause glare and is easily distinguishable from other vehicle lights, enhancing safety on the road.
Blue reflectors on the road typically indicate the location of a fire hydrant or a nearby water source for firefighters to use in case of emergencies. They help emergency responders quickly locate these resources, especially during nighttime or low visibility conditions.
