Car lights sometimes flicker due to poor contact in the lights, wiring, or switches. You can directly visit a 4S shop for inspection and repair. If the entire vehicle is under warranty, the headlight assembly can be replaced for free, as the headlights share the same warranty as the whole vehicle. Car headlights, commonly known as "headlamps," are responsible for nighttime driving illumination and can be considered the eyes of the car. Precautions: 1. The "soul" of the headlight is the bulb. Its performance directly affects nighttime illumination and driving safety. Therefore, high-quality headlight bulbs should be used to ensure safety. 2. Low-quality headlights have the following hazards: (1) Low-quality bulbs have a short lifespan and cannot guarantee stable quality. (2) High-quality bulbs have good light distribution, high brightness, while low-quality bulbs lack sufficient brightness, poor focus, and short range. During overtaking, they can cause visual illusions for the driver, leading to accidents. (3) Low-quality headlights, due to poor sealing, are prone to water ingress during rain or car washing, causing fog inside the lamp. In severe cases, this can lead to short circuits and fires. Therefore, when modifying headlights or replacing them due to damage, never consider low-quality bulbs.

How many types of oxygen sensors are there?

The types of oxygen sensors include: standard oxygen sensor, air-fuel ratio sensor, and nitrogen oxide sensor. The working principle of an oxygen sensor: it uses a ceramic sensing element to measure the oxygen potential in a heating furnace or exhaust pipe, calculates the corresponding oxygen concentration based on chemical equilibrium principles, thereby monitoring and controlling the air-fuel ratio of combustion in the furnace to ensure product quality and compliance with exhaust emission standards. Oxygen sensors are installed both before and after the three-way catalytic converter. The one installed before is called the front oxygen sensor, and the one installed after is called the rear oxygen sensor. The main function of the front oxygen sensor is to detect the oxygen content in the exhaust; the ECU can adjust the air-fuel ratio based on the data received from the front oxygen sensor. The main function of the rear oxygen sensor is to detect whether the three-way catalytic converter has failed.

What is the thickness of automotive sheet metal materials?

Automotive sheet metal materials have a thickness of 0.7mm. The methods for automotive sheet metal repair include: the pleating method, which is used to repair stretched and deformed areas. During the repair process, some pleats are created in the stretched and deformed areas. The pleated areas will be slightly lower than the surrounding areas. After filling with putty, smooth it with a file and then apply paint. The heat shrinking method involves heating the area that requires sheet metal work. When the temperature rises, the steel plate will expand outward, creating stress on the surrounding areas. As the temperature continues to rise until the metal softens, the surrounding steel plate will return to its original shape. Methods for maintaining automotive paint include: 1. Wash the car after the engine has cooled down; 2. Minimize exposure to direct sunlight; 3. Clean any stains on the car body promptly; 4. Rinse with clean water after rain to prevent acid rain corrosion; 5. Apply wax or glaze coating.
