在油价不断高涨的现代社会中，大多数人渐渐的已经减少开车出门的频率了，由于近年来，关于节能减碳方面的重要课题，已被人们所重视，在上下班的交通工具选择上很多人已经选择较为省油的机车、电动机车或是自行车等骑乘车辆作为代步工具。其中尤其是自行车，不但在平日可以当作代步的工具，到了周末假日，自行车更是一种休闲运动。In a modern society where oil prices are constantly rising, most people have gradually reduced the frequency of driving out. In recent years, the important topic of energy saving and carbon reduction has been paid attention to by people, and there are many options for transportation to and from work. People have selected more fuel-efficient locomotives, electric locomotives or bicycles and other riding vehicles as means of transportation. Especially bicycles, not only can be used as a means of transportation on weekdays, but also a kind of leisure sport on weekends and holidays.

但是，在一般的自行车结构设计上，由于自行车本身并不像汽车一样在车头部份设计有车头灯的照明设备，因此，使用者在夜间骑乘的时候，常常因为视线不佳而发生意外。因此，渐渐的有使用者为了增加夜间骑乘自行车时的照明，而在自行车的车头设置有照明灯具，以增加夜间行车时的照明，减少意外的发生。But, on general bicycle structural design, because bicycle itself is not designed with the lighting equipment of headlight in the front part like automobile, therefore, when the user rides at night, accident often occurs because of poor sightliness. Therefore, there are gradually users who are provided with lighting fixtures at the front of the bicycle in order to increase the lighting when riding a bicycle at night, so as to increase the lighting when driving at night and reduce the occurrence of accidents.
