Why Does the Car Key Get Hot After Being Pulled Out?

This is a normal phenomenon. The heating of the car key is directly proportional to sun exposure. The car ignition lock is made of metal, and the hotter the sun, the more heat it absorbs. The temperature inside a closed car under direct sunlight can reach over 80 degrees Celsius. The thin car key inserted into the lock hole will quickly heat up, hence the car key becomes hot. The light above the car keyhole: There is a light above the car keyhole, and it's not an LED. With a lower color temperature, it emits a warmer light. After prolonged exposure, the car key heats up. Magnetic field changes: For car keys with anti-theft chips, after the key turns the ignition switch, the factory-installed electronic anti-theft system automatically detects it. The magnetic coil inside the ignition switch may generate heat due to changes in the magnetic field, causing the car key to heat up. This is a normal phenomenon. The excessive current passing through the ignition switch (except for the high current of the starter motor, which does not pass through the intermediate relay for safe conversion).

Can Halogen Car Lights Be Directly Replaced with LED Bulbs?

Halogen lights cannot be directly replaced with LED bulbs. To switch from halogen to LED, the entire LED light assembly must be replaced. Simply changing the bulb alone is ineffective. If the original vehicle lacks a projector lens, it is advised not to modify the lights, as the improvement would be minimal and could cause glare for the driver, impairing visibility and posing significant safety risks. LED car lights are suitable for various automotive lighting applications, including: headlights (high beam and low beam), fog lights, taillights, brake lights, turn signals, daytime running lights, footwell lighting, instrument panel lights, license plate lights, door lights, interior lighting, position lights, navigation, entertainment systems, backlighting, and indicator lights.

How Many Years Until a Vehicle is Mandatorily Scrapped?

For non-commercial small passenger vehicles, there is no mandatory scrapping age as long as the vehicle passes the annual inspection. However, when the vehicle's mileage exceeds 600,000 kilometers, it will be guided for scrapping. Once the vehicle reaches 15 years of age, the inspection interval is shortened to every 6 months. Below is additional information on vehicle scrapping: 1. The inspection cycle varies depending on the vehicle type and condition. For small private vehicles, inspections are required every 2 years within the first 6 years, annually from 6 to 15 years, and every 6 months after 15 years. It's important to note that 'exemption from inspection within 6 years' does not mean no annual inspection is required; it means exemption from the on-site inspection. 2. If the driver has poor driving habits or improper maintenance, and the vehicle fails to meet performance standards during inspection, it may be 'prematurely scrapped'.

Can I take Subject Two immediately after passing Subject One?

To pass the Subject One driving test, a score of 90 or above is required. The test consists of 100 questions, divided into single-choice and true/false questions, with each question worth 1 point, totaling 100 points. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," if a test-taker answers 11 questions incorrectly, the system will automatically submit the test and end the examination. Subject One, also known as the theoretical driving test or driver's theory test, is part of the motor vehicle driving license assessment. The test content includes driving theory basics, road safety laws and regulations, local regulations, and related knowledge. The test is conducted on a computer with a time limit of 45 minutes. Subject One test content: regulations on driving licenses and motor vehicle management; road traffic conditions and regulations; road traffic safety violations and penalties; regulations on road traffic accident handling; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized passenger and freight vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject One test precautions: Candidates should pay attention to their attire, avoid wearing slippers, and are not allowed to bring electronic devices or bags into the examination room. They must bring their ID card and queue to enter the waiting hall. Observe the precautions and procedures on the large screen, and store personal belongings in a locker before entering the examination room. In the examination room, candidates will be assigned a seat at the identity verification area. After finding their seat, they can begin the test. Ensure the camera is aligned correctly and adhere to exam discipline. If a candidate fails the first attempt, they can retake the test the same day. If they fail again, they must pay to reschedule. After the test, candidates must queue to collect their score report and sign it; unsigned reports are considered invalid. There is no limit to the number of times Subject One can be scheduled. Each subject can be taken once, and if a candidate fails, they can retake it once. If they do not attend the retake or fail the retake, the examination process ends, and the applicant must reschedule. However, Subject Two and Subject Three have only five examination attempts each. Subject Two and Subject Three tests must be scheduled at least ten days apart. If a candidate fails the Subject Three safe and civilized driving knowledge test, the previously passed road driving skills test results remain valid. The driving test consists of three subjects: Subject One, Subject Two, and Subject Three. Subject One refers to the examination on road traffic safety laws, regulations, and related knowledge. Subject Two refers to the field driving skills test. Subject Three is divided into two parts: road driving skills and safe and civilized driving knowledge. The safe and civilized driving knowledge test is conducted after Subject Three, so it is commonly referred to as Subject Four. However, in official terms (i.e., the Ministry of Public Security Order No. 123), there is no such thing as Subject Four.

Will the Bulb Catch Fire If Left On Continuously?

Leaving the bulb on continuously will not cause a fire. Keeping the lights on for an extended period is not prone to causing a fire, but it can easily lead to a drained vehicle battery. The capacity of a vehicle's battery is not very large, and prolonged use of the lights will deplete the battery's charge, significantly affecting the battery's condition and the vehicle's normal operation. The vehicle battery's capacity is primarily designed to ensure the car can start normally, as the engine requires sufficient power during the startup process. Once the engine is running, the power supply is entirely taken over by the generator. If the vehicle's lights remain on, the battery can become drained within a few hours.

What to Do When Rearview Mirrors Are Unclear in the Rain?

Solutions for unclear rearview mirrors on rainy days are as follows: 1. Rearview Mirror Heating Function: Many modern cars are equipped with a rearview mirror heating function, which uses embedded heating wires behind the mirror to raise the surface temperature, accelerating water vapor evaporation. 2. Install Rain Guards: Not all cars have heated rearview mirrors. For vehicles without this feature, installing rain guards is an option. These can keep the mirror clear in light rain and ensure at least one-third visibility in heavy rain. 3. Apply Water Repellent: The main component of water repellent is silicone oil, which alters the surface tension of the glass, making the rearview mirror water-resistant. After application, rainwater forms round droplets that can be easily shaken or blown off. However, reapplication is needed every few months. 4. Use Laundry Detergent or Soap: Apply a clean, wet cloth or sprinkle laundry detergent, then spread it evenly on the rearview mirror. Wait a few minutes for it to dry, then wipe clean with a tissue. This method is not suitable for long-term use but is convenient and low-cost.
