they reflect the light using the law of incidence
Cats eyes
"cats eyes" are reflective pieces of equipment that help you see where the lanes are at night. your car's headlights reflect off of them so you can spot them easily.
Yes, that is their purpose.
If you're referring to the objects in the centre of the road - that are sometimes called cats eyes, then it's reflected light. No cats were harmed in making them.
Both the cat's eyes and safety markers are capable of reflecting light .
Cats eyes are used on a motorway to serve as a retroreflective safety device and as road markings. Amber cats eyes, in particular are used in the United Kingdom and Hong Kong and are placed along the edge of the central reservation.

Cats eyes can be any colour, but the colours normally used on public roads in the United Kingdom (possibly different in other countries) are white between lanes, red to mark the left edge of the road and green Is commonly used to mark where a slip road leaves or joins.
The invention was trialled on a road in England and it was a success
