Can modified LED headlights pass the annual vehicle inspection?

Modifying car headlights to LED is similar to converting to xenon lights, as long as the color temperature, brightness, and beam angle meet the requirements. The annual inspection has the following requirements for lighting: 1. Color temperature: The light color temperature must not exceed 6000K. 2. Brightness: The low beam must not be below 1050 lumens, and the high beam must not be below 1450 lumens. 3. Beam angle: The use of headlights must not affect other road users, and the light height must not be too high. Below are other legal regulations regarding car modifications: 1. The new "Road Traffic Safety Law" clearly stipulates that no unit or individual may assemble a motor vehicle or alter the registered structure, construction, or characteristics of a motor vehicle without authorization. The structure of the vehicle includes the body color, length, width, height (four rigid standards), and the relevant technical parameters of the engine. 2. Before modifying a licensed vehicle, the owner must register and declare the modification to the vehicle management office. The modification technical report must be reviewed and approved by the vehicle management office before the modification can proceed. After the modification is completed, the owner must also complete the modification change procedures at the vehicle management office. 3. Whether a vehicle modification is legal depends on whether the vehicle matches the photo on the vehicle registration certificate and whether it complies with the factory technical parameters. If it does not comply, the vehicle will not pass the annual inspection.

Which wire is the ground wire for the new Polo's taillight?

New Polo taillight ground wire is: The ground wire for the new Polo's taillight is the black wire. Open the taillight circuit board, and the wire that connects to all the bulbs is the ground wire. The ground wire in a car is the negative terminal of the battery connected to the car body, so the entire car is electrified. Electrical devices are installed on the car body, with one end connected to the positive terminal, and the negative terminal is conducted through the car body. The ground wire (negative) is the part connected to the car body. Here is more information: 1. The ground wire in a car refers to a current return line. The power comes out from the positive terminal of the battery, passes through various switches and electrical actuators, and then returns to the negative terminal of the battery through a return wire, forming a cycle that enables the electrical devices to perform various actions and functions. Cars use a single-wire system, meaning most wires carry their own power. 2. The return wires of various electrical actuators do not go directly to the negative terminal of the battery but indirectly return to the negative terminal through the car's own metal body. Any wire connected to the car's metal body can be collectively referred to as a ground wire.
