rear light unit in astra 2005?

I don`t think it is too bad a job and if you take your time you will get on fine,look in your boot behind the light unit,I think they are white plastic wing nuts,remove llight unit,press on the release lug on the wiring connection and pull off and look for plastic lugs to squeeze in to release the bulb holder from the unit,refit in reverse,good luck
