55 plate mine does come on, sorry.
Car locked, unlock with remote, all 3 lights, front middle back, come on. open front door and get in close door back two lights go out straight away front dims after 30-40secs, or if you put key in and turn, goes out then.
Is it to do with what light you have there. I have got the sunroof and the single big light with 3 position switch in each location. But I think some without sunroofs have the map reading left/right lights. haven't got any pictures to show what I mean so I hope I made it sound clear.
