I can imagine driving a buggy at night on the street with no lights and no reflectors is very dangerous. Perhaps some kind of less garish reflectors might be a good solution. I would guess that the religious principles of drawing undue attention would not be violated by reflectors that were not very noticeable except at night with headlights shining on them.
Ive come up on a buggie at night, especially this time of year when the days are short and Im glad they have the orange reflectors. I cant imagine driving on a windy country road a night and coming up on a slow moving horse and carriage with no reflectors
Interestingly one day I stopped at a grocery store near work that has special Buggie Only parking and, Im not making this up, there was an open buggie parked that had a bright red gasoline can in full view in the back.
That was almost as strange as the afternoon I was leaving a golf driving range in NE Maryland and saw a pickup truck some sort of work truck, drive up with two black guys and a young Amish guy. They came to play putt putt.
