I completely agree! In my other cars, I changed or installed beside a DIN 12V socket and all devices I am using in the car have got the responding plug. This is save solution. For use in other cars (e.g. rented cars) I have an adaptor DIN<->cigarett-lightener socket, Just a short cable.
However, there are plugs for the cigarett-lightener socket very well made, fitting tight and staying on its place save fixed. I have got such in shops with electronic stuff.
The torch mentioned just fits well in design and function, and is a kind of "alibi" for the original cigarett lightener socket, as I didnt want to pull it out.
