1. Headlights
Headlights include high beams and low beams, which are the most important components of the whole set of car lights. Checking the lights first ensures that the headlights can be used normally. In addition to the lighting function, headlights can also let other drivers and passers-by know your presence. For various reasons, some drivers choose not to repair the low beams even if they are broken, but replace them with high beams. This can easily cause oncoming vehicles to not see the road conditions clearly because your lights are too strong, thus causing dangerous situations. Moreover, the traffic law also stipulates that high beams cannot be used for a long time unless necessary. We can judge whether the headlights are normal or not by changing the intensity of the lights.
2. Turn signal
When driving on the road, the turn signal is the most important equipment to inform other vehicles of your movements, so we must confirm whether the turn signal is normal or not before driving. When driving, you can use the sound frequency of the relay to judge whether the turn signal is normal, or you can visually check around the vehicle.
3. Taillights
In addition to headlights, taillights are also important equipment to let other drivers and passers-by know you are there. We must confirm whether the taillights can be used normally to better avoid rear-end collision accidents.
4. Brake lights
Brake lights are generally installed at the rear of the vehicle. The main color is red, so that the vehicles behind can easily find the brakes of the vehicle in front, which plays the purpose of preventing rear-end collisions. With the help of other people or walls and 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 bulbs are on, whether the sensor switches are normal is also a part that must be checked, so the front and rear brakes must be pressed to confirm whether these switches are working normally.
5. Instrument
The main thing to pay attention to when using the instrument is whether the warning lights are on, the pointer is rotating, and whether the LCD display is abnormal. When you turn the key switch, you will find that the lights on the instrument will first light up and then go out, and the pointer will move completely. At this time, we must confirm whether the pointer moves smoothly and whether the various signal lights are on, especially the three warning light signals of the computer fault light, oil light, and voltage light.
