and again: Change the lamp at the rear

Hello to each other, now’s me also caught, one of the 4 stand light lamps at the back (left, top) of my v70, year 2002 is gone. Everyone who reads and writes here knows how stupid the things (the top) are to change. To prepare the action I have read most threads here on the topic. My questions would be: 1. Are there new insights for a painless change of the lamp without the 2. Maybe someone has developed in the meantime a clever lamp change tool 3. Do I really assume that I should reach the relevant lamp manually to the left, as with the usual bayonet lock must turn ? Do I have to solve before any cables on the lamp socket or can I turn all the stuff out in one? Thank you dear community for suitable tips!
