Can anyone help me at all?  I have an N reg Fiat Punto Sporting and the
lights have been doing my head in recently.  The rear side light stops
working after a few days.  I take the back light panel off and pull the wire
plug out, then normally when I plug it back in the light if back on again.
It has done this on the other side with the brakes before but the bulb was
loose and so was the wire (I think the speed jhumps I have to navigate to
work and back every day knock them out sometimes).  However today I have
disconnected the lights and reconnected them again and nothing!  

I will try wiggling the blub in case it's loose and I think I have a new one
just in case it's blown but why do the lights keep playing up?  Has anyone
else had this problem?

Any help would be apprceiated.
