Can Halogen Lights Modified to Xenon Lights Pass Annual Inspection?
3 Answers
Currently, there are no explicit laws in China that classify modifying halogen lights to xenon lights as illegal. However, if the luminous intensity of the modified xenon lights exceeds the specified limit, it is considered an illegal modification. Moreover, vehicles with halogen lights modified to xenon lights cannot pass the annual inspection. Below is a detailed introduction to xenon lights: 1. Xenon lights, also known as High-Intensity Discharge (HID) lights, offer advantages such as safety, energy efficiency, high brightness, long lifespan, and easy installation. Many high-end vehicles come equipped with xenon lights from the factory, making them a popular choice for car light modifications. 2. There is no issue with xenon lights as long as the color temperature does not exceed 6000K during installation. The standard color temperature for factory-installed xenon lights is 4300K, which provides the best light penetration without causing glare to oncoming traffic.
I often encounter car owners consulting about the troubles of headlight modification. In China, the annual vehicle inspection has strict requirements for lighting. If you replace halogen lights with xenon lights, you must add lenses. If the light source is scattered or unfocused, the inspector will judge it as non-compliant and fail the annual inspection. Common mistakes include excessive brightness or light scattering after modification, which can interfere with the vision of other drivers. I recommend choosing a dedicated lens kit for modification and keeping the brightness within 5500K. Without lenses, the risk is high, and failing the annual inspection will cost more time and money to fix. After modification, it's best to have a pre-check at a lighting test station. Keeping the original headlights as a backup is a wise practice. Safety first, and only compliant modifications can save you from unnecessary troubles.
I've been into car modifications for years, and whether xenon headlights pass annual inspection all comes down to the details. Installing them without projectors will definitely fail the test because the light scatters too brightly, posing safety hazards. During inspections, beam angle and color temperature are the key points - exceed the limits and you're stuck. I once helped a friend modify a set of lights with properly adjusted projectors that passed smoothly. During installation, the circuitry must be matched correctly to avoid false vehicle alerts. It's best to choose certified projector products to save money and hassle. Going to a professional shop for installation and adjustment reduces risks. DIY attempts often lead to mistakes and inspection failures. Modifications are fun, but must follow the rules.
