The original window switches on the XJ40 were screen printed with the window icon and arrows.  Over time, and many presses, these have often worn away or faded badly.
 
These decals offer a cheap (if non-original) way to improve the image of these switches.  These are for best for switches that do not have back illumination and they are not transparent, although they can be used on either.
 
Supplied as a set of eight for the driver's door and all other...either left or right hand drive.  A clever idea suggested by a customer of mine...brilliant!
