how do i change the reverse light on a fiat punto ?

Depends on which style punto it is. I used to have one and to change the lights in the back columns you had to open the boot, unscrew, remove the screw covers and undo a couple of screws to release the whole of the lighting section, it then should unclip/unscrew and bulb can be replaced then obviously everything screwed back into place. Not sure if this is of use as my Punto might have been older than yours. Of course, if worst comes to worst, turn up at your local garage and just ask someone to tell you how to do it, 9 times out of 10 they will just do the job for you lol
