My old 1955 VW Beetle with a small rear window, and semaphore indicators, had 6 volt electrics and headlights like candles. On one occasion the battery power was so low in a rain storm at night, I disconnected the windscreen wiper motor and tied string to the wiper blades and passed the string through the quarter light, across the dash and out the other quarter light, back to the other wiper, allowing me to pull the string in both directions and operate the wiper with one hand, steer and change gear with the other, and peer into the darkness to get me home.
The indicators would stick both down and up and to help the 6 volt electrics a good thump on the door pillar behind the Semaphore unit did the trick. But to do that while you were driving along was not so easy as the door post was just behind you.
The front brakes were drum brakes and were very slightly oval so when you jumped on the brakes, within half a turn they would lock up. The only problem was that the front passenger seat was one that folded forward twice, the back rest folded onto the seat and the seat folded forward into the front leg well, and there were no catches or seat belts. When I came to sell my VW I took the buyer and his friend out for a short drive to show them how it went. On the way back they asked about the brakes so I showed them how good they were, Jumped on the brakes, they locked up and both passengers ended up with their faces on the windscreen, in a heap in the front leg well. They were well impressed.
The six volt electrics also meant that the starter motor was US, so I always parked the car at the top of our steep drive or on a hill facing down, so I could bump start it.
Those were the days
