‘Going with God,’ conservative Amish sue Ohio over lights law
In the 1960s, the Swartzentrubers — one of the most conservative subgroups of Old Order Amish — worked out a deal with the Ohio government: instead of marking their vehicles with an orange slow moving vehicle emblem and bright battery-operated blinkers, they would instead stick reflective tape on their buggies and use kerosene lanterns as headlights.
That agreement stood for decades.
