:No bad, but could you show how it retract when a car goes over it. Anyway we want a real photo as well.  

  
 BTW According to http://www.design-technology.info/inventors/page14.htm the correct name is Catseyes as it is trademarked, and after a further search I found http://www.jenkins-ip.com/mym/spring2000/t_news01.htm which says - 

 :"Of course, when thinking of a name for his product, Shaw returned to his original inspiration. He therefore called his device the Catseye road reflector. With the passage of time, this name has become extremely well known, at least in the UK. Further, from the nature of its use by the public, you would think that it had entered into the language as a generic term for such road reflectors. Indeed, the term “cat’s eyes” appears in Roget’s Thesaurus, whilst “Cat’s-eye” is found in the Oxford English Dictionary. Care should be exercised, however, before making such assumptions. On closer inspection, the OED states that Cats-eye is a proprietary name and this is confirmed by a review of the UK and CTM registers where Catseye (one word) is found to be protected in Classes 6, 9 and 17 and in the ownership of Shaw’s original company, Reflecting Roadstuds Ltd.
