1. The role of positioning lights
Positioning lights, also known as position lights and vehicle width lights, are also commonly known as small lights. The purpose is to allow other passers-by to judge the size and location of the vehicle when the headlights are not turned on and the sky is dim. There is a mandatory requirement for cars to match positioning lights on the left and right sides to indicate the width of the car, while motorcycles can be designed with left-right symmetry or a single positioning light in the center. (You don't want to be hit by the roadside in the dark, do you?)

2. Is it okay to turn on the positioning light for cycling at night?
The brightness of the positioning light is low, it is almost invisible during the day, and the visual distance is limited at night. More importantly, the brightness of the positioning light cannot illuminate the road ahead, and you cannot ride normally.
Positioning lamp does not have lighting effect

3. Do you need positioning lights when the headlights are turned on?
After turning on the headlights, the function of the positioning lights is replaced by the headlights, and there is really no need for positioning lights. However, headlights consume high power, so many locomotives will design to only turn on the positioning lights after power on (for example, motorcycles: there are 3 bulbs in the large and small eyes, and the small eyes are the high beams turned on separately; Big eyes include positioning lights and low beam lights. After power is turned on, the positioning lamp is turned on, and the engine is turned on with the low beam. The handle controls the other big eye to light up the high beam ~), the shape of the positioning lamp can also become one of the characteristics.
The headlights are turned on, and the function of the positioning lights has actually declined.

4. The role of daytime running lights
Since studies by traffic control departments in various countries have shown that turning on the lights during the day can improve visibility and reduce accidents, there is a mandatory provision for daytime running lights. Some national laws and regulations require that if daytime running lights are not designed, low beam lights can be forced to be turned on instead, which is why the imported cars we ride cannot turn off the lights. It is a pity that there seems to be no such law mandatory for motorcycles in our country at present. Most passing locomotives have light group switches, which can be turned off instead of always on. In actual riding, it is dark in rain, dark in evening, dark under overpass and dark through caves. I hope you can form good safety habits and keep the lights always on ~ it's nothing if you break a few bulbs. It's much worse to be hit than changing bulbs!
Even in the case of some backlighting in the big sun, the daytime running lights have a high degree of recognition.

5. Are all LED lights other than headlights daytime running lights?
Because of the high brightness of the LED, it has become a common light source for daytime running lights, but the LED is not necessarily a daytime running light. As long as the brightness does not meet the requirements, it can only be called a positioning light.
6. Do you still need a low beam set with daytime running lights?
No, the daytime running lights can be replaced by a constant light group. Due to the special daytime running lights, the low beam lights can be turned off compared to other locomotives that generally have constant low beam lights.

7. Can I only turn on the daytime running lights when cycling at night?
Although the brightness of the daytime running lights is high, there is no light distribution regulation required for the low beam, and the daytime running lights cannot produce an effective light pattern to illuminate the road. the use of daytime running lights, other passers-by, vehicles can see you, but you can't see the road... night vision eye don't wrangle!

1. Headlights
Headlights include high-end lights and low-end lights, which are the most important part of the entire set of lights. Check the lights to ensure that the headlights can be used normally. In addition to the function of lighting, headlights can also let other drivers and passers-by know your existence. For various reasons, even if the near light is broken, individual drivers choose not to repair it, but to replace it with the far light. This can easily cause the on-coming car to be unable to see the road because your light is too strong, which leads to dangerous situations. Moreover, the traffic law also stipulates that high beams cannot be used for a long time if it is not necessary. We can judge whether the headlights are normal or not by changing the light intensity.

2. Direction light
When driving on the road, the direction light is the most important equipment to inform other vehicles of their own movements, so we must confirm whether the direction light is normal or not before driving. When driving, you can use the sound frequency of the relay to determine whether the direction light is normal, or you can perform visual inspection around the vehicle.
3. Tail light
In addition to the headlights, the taillights are also important equipment for other drivers and passers-by to know your existence. We must confirm whether the taillights can be used normally to better avoid rear vehicles collision accidents.

4. Brake light
The brake light is generally installed at the rear of the vehicle, and the main color is red, so that vehicles driving behind can easily find the brakes of the vehicle in front to prevent rear-end collisions. Through the help of other people or walls or other reflective objects, we can see whether the brake lights are on when we press the brake. In addition, it should be noted that in addition to whether the light gun is on, whether the sensor switch is normal is also a part of the check, so the front and rear brakes must be pressed to confirm whether these switches operate normally.

5. Instrument
The main points to be paid attention to are whether the warning lights are on, whether the pointer rotates and whether the liquid crystal display is abnormal. When the key switch is turned off, it can be found that the lights on the instrument will be fully on and then go out, and the pointer will be fully activated. At this time, we must confirm whether the pointer operates smoothly and whether each signal lamp is on, especially the three warning lamp signals of computer fault lamp, oil lamp and voltage lamp.

6. Summary
No matter what type of light bulb, once a failure occurs, it will not appear slowly like a mechanical failure, but will occur suddenly and without warning, and the damage of the lamp may also damage other related electronic accessories. Therefore, every time before the road, you should check the lights to ensure that all parts of the normal action. In addition, if you need to replace the lamps, try to choose a professional vehicle maintenance point, both safe and worry.
