What is Cat's eye (road)?
[[File:M9 motorway Carlow Ireland catseyes.jpg|thumb|A motorway, in Ireland, at dawn. The small things in yellow and white are cat's eyes.]] In the context of road signalisation, '''cat's eyes''' is the name for special [[reflector]]s. When [[light]] shines on them, they will reflect it back in the same direction. Usually they are small [[cylinder]]s. Very often they signal the presence of objects or they alert the driver of a danger such as a bend in the road. {{stub}} [[Category:Transport infrastructure]]
