What are stained glass and leadlights?

 
  Stained glass and leaded lights are panels of glass joined with strips of came, traditionally lead came.  

Stained glass and leadlights, sometimes called leaded lights, are joined pieces of coloured and plain glass used to create a picture or shape. ‘Stained’ glass refers to glass which is coloured or painted; leadlights refer to all glass panels which have been joined with came. The names are often used interchangeably, with leadlights usually being the simpler designs found in homes and stained glass being the more intricate designs seen in churches.
