Hi have had the car in storage over winter first mistake

.
Currently none of rear lights and also boot not working. I also get bulb failure error on dash.
If a bulb fails would it stop all of the lights at the rear working??
Car is booked in for morgan service but not for another few weeks as they are booked up.
Wondered if any suggestions on anything I can do in the interim. I checked the fuse box but couldnt work out from the labels which fuse might relate to this (if indeed it's a fuse)
Also tried usual disconnecting and reconnecting battery trick, which normally cures other electrical foibles.
Thanks,
Reuben
