However, whether it is a positioning light or a daytime running light, it is a light group designed outside the headlights and headlights. What is the difference between the two? It seems that both are very similar, Xiaobian now let you distinguish the difference between the two, don't call the wrong name again. 
Positioning lights, also known as position lights, width lights are also commonly known as small lights, the purpose is to allow the vehicle to determine the size of the vehicle without the headlights and dim sky.
The car part has mandatory provisions for positioning lights on the left and right sides to indicate the width of the car. Motorcycles are either left-right symmetrical or central single-position lights. 
No, the brightness of the positioning lamp is relatively low, and it is almost invisible during the day. The viewing distance is limited at night. More importantly, the brightness of the positioning lamp cannot illuminate the road ahead. The positioning lamp is often an auxiliary function on the light source.
In addition, if you stop at the roadside when the sky is dark, it is quite a waste of gasoline to start the engine. In addition, in the design of the vehicle, the shape of the positioning lamp can also become one of the characteristics of the car, which can highlight the style of the vehicle and further enhance the recognition of the vehicle.
What is the role of the daytime running lights? 
What is the difference between daytime running lights and positioning lights? 
For example, in Taiwan, the daytime running light in front of it is not less than 400 candles, and the luminosity in any direction should not exceed 1200 candelas, and the color is white.
Under normal circumstances, the most important function of daytime running lights and positioning lights is to let others recognize the vehicle, but the brightness of daytime running lights is mostly higher than the width of the lights. 
Not necessarily, because the brightness of the LED light is high, it will generally become a common light source for daytime running lights, but the LED light is not necessarily a daytime running light. As long as the candle light does not meet the requirements, it can only be called a positioning light.
Is there a daytime running light that also needs a constant low beam?
The best examples are DUCATI's recent models, such as the SuperSport all-car, the XDiavel S, etc. Thanks to the daytime running lights, SuperSport and XDiavel S are compared to other models that are commonly used for permanent low beam. The headlights are available for shutdown. 
Can I only turn on the daytime running lights when I ride at night? 
No, although the brightness of daytime running lights is high, there is no light distribution requirement for headlights. Simply put, daytime running lights cannot produce effective light patterns to illuminate the road surface. Although daytime running lights are on, other passers-by see You, but you will not see the way.
In the car, most new models have been equipped with daytime running lights, but so far, only a small number of motorcycles have daytime running lights, while daytime running lights and positioning lights are not the same thing.

Teach you how to distinguish motorcycle daytime running lights and positioning lights
The lamp system is a very important part of the vehicle. In addition to the headlights, direction lights and taillights, the general vehicle will also use the positioning lights or the running lights to make a finishing touch to the exterior of the vehicle. After the headlights are lit, do you still need to position the lights?
What is the role of the positioning light?
Is it only possible to drive the positioning lights at night?
When the headlights are turned on, the function of the positioning lamp is replaced by the headlights, so the positioning lights are not needed after the headlights are lit. However, the headlights are quite power-hungry electrical systems. Therefore, many models will be designed to open the electric door only when the electric light is turned on, and the headlights are turned on after the engine is started.
(daytime running light above Ducati XDiavel S)
As national studies have shown that daylighting can make the vehicle stand out in the background, improve visibility and reduce accidents, so there are regulations for daytime running lights. In fact, the headlights are also a kind of flexible design of daytime running lights. Many local regulations require that if the vehicle is not designed with a running light, it is necessary to force the headlights to be replaced.
(Even in the strong light, XDiavel S's daytime running lights still have a high degree of recognition)
Although the daytime running lights and positioning lights of motorcycles can also be single-lamp design or double-lamp design, because the daytime running lights must be clearly visible during the day, and can not make the incoming car or passers-by glare, therefore, for the brightness There are also certain standards, and the brightness requirements of daytime running lights vary from region to region.
Are LED lights other than headlights daytime running lights?
(Guangyang flagship pedal AK550 positioning lights for LED lamps)
No, as mentioned earlier, the daytime running lights can be replaced by the constant-light low beam group. Conversely, with a fixed daily daytime running light, the normally bright low beam group is not necessarily required.
