Clear by now surely that L is normal to applied E. And btw, just as clearly, relative velocity (re gamma factor) is also taken as normal to E, hence along the same axis as L.
Well, it's clear now that you've said so. So now my question is, how is L measured? Since it's normal to E, it isn't linked directly to something obviously physical like the distance between the capacitor plates. So how is L measured?
