The Notes in the July 1898 issue of the British magazine The Observatory include this little story:
"A gentleman was summoned at Altrincham for riding at 8.40 P.M., on April 3, without a light."
The defendant argued he was riding legally, since the effects of longitude and latitude on sunset time had not been taken into account.
The summons was dismissed.
(The puzzle at the bottom of the page shows how new the bicycle was in that era.)

The article triggered a series of letters continuing into early 1899. (The indices are in inverse chronological order.)

I was not ambitious enough to calculate the actual Sun altitude at the time and place.
