I used to have a German desk lamp which used a 6V automotive bulb (I believe that in its day 6V Beetles were still common). It had a transformer in the base, a telescopic arm, and a 2-pin plug.
Depending on which way I plugged it into an adapter (before I put a 1363 on it) I could get that not-quite-a-tingle-but-a-slightly-"sticky/rough" feeling when dragging a fingertip lightly along the telescopic arm. (Body & shade were plastic).
