Yep, see below - although I'm sure you'll have already seen them yourself:
Description of Panzer Magnetlampe: https://www.tapatalk.com/groups/missinglynx/magnetlampe-in-panzers-t53887.html
Reference to Magnetlampe storage tin: https://www.shapeways.com/product/XMN8A8LW6/1-16th-generic-interior-panzer-parts-1
I also found another description of the Magnetlampe that confirms the one in the first link but I can't find that page again, sorry.
