I'm amazed that no one answered the question - there's also a "R" switch ("Reserve") which you can turn on when you're low on fuel (or try to launch in the Winter) - so it was something like low fuel light nowadays, but manual (it was placed lower in tank than regular fuel drain) And yes, to know exact fuel status you had to lift up the hood and check ;) I am / was (still have Trabi at my parent's place, but haven't ride it for ~5 years) proud Trabi owner, AMA :)
