When traveling on a road at night (meaning the period from sunset to sunrise; the same applies hereinafter in this Article and Article 63-9, paragraph (2)), a vehicle must have its headlights, road lights, taillights, and other lights turned on pursuant to Cabinet Order. The same applies at times other than night in cases that Cabinet Order prescribes.
車両等は、夜間（日没時から日出時までの時間をいう。以下この条及び第六十三条の九第二項において同じ。）、道路にあるときは、政令で定めるところにより、前照灯、車幅灯、尾灯その他の灯火をつけなければならない。政令で定める場合においては、夜間以外の時間にあつても、同様とする。
The driver of a vehicle or streetcar must turn off or reduce the brightness of its lights or otherwise operate them in accordance with Cabinet Order at night (or in a case as referred to in second sentence of the preceding paragraph) when there is an oncoming vehicle or streetcar and when traveling behind another vehicle or streetcar, if the brightness of those lights are likely to interfere with vehicle or streetcar traffic.
