Reflecting Roadstuds is the main company in the UK that manufactures cat's eyes for use on roads.
Percy Shaw, of Halifax (then in the West Riding of Yorkshire) invented the cat's eye.
It required £500 from two company directors and established a 20-acre (81,000 m2) manufacturing site with 130 workers, later making a million roadstuds a year.
[1] Initially it was difficult for the company to sell their new idea to road constructors and the government.
Roadstuds, also known as raised pavement markers, are also made by Roadcraft Safety Products of Weston-super-Mare.
