       5 . The stair nosing as claimed in  claim 1  characterised in that the or each sign is held in place by being directly applied to a back face of the window, alternatively the second section and window are configured to co-operatively retain the or each sign between them. 
   
   
       6 . (canceled) 
   
   
       7 . The stair nosing as claimed in  claim 1  characterised in that the or each sign includes one or more feature selected from the group consisting of: a glow strip, arrows, markings, safety advice, sponsors logos, other advertising and a combination of these features. 
   
   
       8 . (canceled) 
   
   
       9 . The stair nosing as claimed in  claim 1  characterised in that the window is configured to be releasably attached to or retained by the second section. 
   
   
       10 . (canceled) 
   
   
       11 . The stair nosing as claimed in  claims 1  characterised in that the second section includes one or more primary engagement means and the window includes one or more secondary engagement means, said engagement means being configured to act co-operatively to releasably attach the window. 
   
   
       12 . The stair nosing as claimed in  claim 11  characterised in that the or each secondary engagement means is configured to hold the sign during assembly of the stair nosing. 
   
   
       13 . The stair nosing as claimed in  claim 12  characterised in that the sign is dimensioned to fit between at least two secondary engagement means or one primary and one secondary engagement means. 
   
   
       14 . The stair nosing as claimed in  claim 11  characterised in that the second section includes a primary groove that is parallel to the longitudinal axis of the stair nosing, such that a peripheral edge of said primary groove overhangs and forms the or each primary engagement means. 
   
   
       15 . The stair nosing as claimed in  claim 14  characterised in that the window overhangs, and is supported by, at least one of the peripheral edges. 
   
   
       16 . The stair nosing as claimed in  claim 11  to characterised in that the or each secondary engagement means extend perpendicular from a primary surface of the window. 
   
   
       17 . The stair nosing as claimed in  claim 11  to characterised in that the or each secondary engagement means includes one or more engagement tabs. 
   
   
       18 . The stair nosing as claimed in  claim 17  characterised in that one or the engagement tab is a distal engagement tabs, such that the distal engagement tab is ante expanded section located at a terminal end of the respective secondary engagement means, such that, during assembly, the or each secondary engagement means is configured to deflect allowing the distal engagement tab to pass the respective primary engagement means, the or each secondary engagement means then returns to its original shape trapping a section of the distal engagement tab behind the respective primary engagement means. 
   
   
       19 . The stair nosing as claimed in  claim 1  characterised in that the first section includes one or more first grooves formed into its exposed surface, such that the or each first groove has a friction modifying material or highly visible material applied to it. 
   
   
       20 . (canceled) 
   
   
       21 . (canceled) 
   
   
       22 . The stair nosing as claimed in  claim 19  characterised in that the or each first groove is parallel to the longitudinal axis of the stair nosing. 
   
   
       23 . The stair nosing as claimed in  claim 1  characterised in that the second section includes one or more sign supports configured to support the sign. 
   
   
       24 . The stair nosing as claimed in  claim 23  characterised in that the or each sign support is in a primary groove formed into the second section, such that the or each said sign support and said primary groove are parallel to the longitudinal axis of the stair nosing. 
   
   
       25 . A system which includes a stair nosing as claimed in  claim 1  and a base plate, said base plate being configured to be cast or formed into a step during construction; such that the first section is configured to releasably attach to the base plate. 
   
   
       26 . The system as claimed in  claim 21  characterised in that the base plate includes a first surface which is left exposed during the construction of the step, said first section being configured to releasably attach to the first surface. 
   
   
       27 . The system as claimed in  claim 1  characterised in that the base plate includes one or more extended sections that extend from a second surface, where the second surface is opposite the first surface, and are configured to retain the base plate in the step. 
   
   
       28 . The system as claimed in  claim 23  characterised in that the or each extended section has a cross sectional shape selected from the group consisting of:— L shaped, arrow shaped, T-shaped and ‘pi’ shaped. 
   
   
       29 . The stair nosing as claimed in  claim 2  characterised in that the hinge includes a semi-circular channel and a matching semi-circular protrusion, such that said channel is configured to releasably engage the protrusion.
