Why Do Xenon Lights Dim After Four Years of Use?
1 Answers
Xenon lights dim after four years of use because the bulbs have aged. Here is some information about xenon lights: How to Determine if Xenon Lights Are Aging: First, observe how quickly the xenon lights start up. If they take more than 4 seconds to reach 80% brightness, it indicates that the xenon bulbs are aging. Second, check if there is any cloudy or solid residue inside the bulb. Aging xenon lights may develop a white, foggy appearance. When to Replace Xenon Lights: Xenon lights typically experience light decay after 2 to 4 years of use, so it's best to replace them shortly after noticing the light decay, usually around the 2-year mark. When replacing, choose a 4S shop or a large, reputable repair shop, as replacing xenon lights involves the car's electrical system. If the technician lacks expertise, it could lead to bulb burnout, car malfunctions, or other issues. Precautions for Xenon Lights: Modifying a car to use xenon lights is considered an unauthorized alteration and violates traffic regulations. If caught, you may face fines and demerit points, and it could affect your vehicle's annual inspection. Therefore, drivers considering upgrading to xenon headlights should think carefully and, if possible, register the modification with the local vehicle management office. Those who have already installed xenon lights should use them with extra caution, as the intense light can cause temporary blindness for about 3 seconds. Additionally, if dust accumulates on the bulbs, it can lead to heat dissipation issues, making it difficult for others to see clearly, which is dangerous while driving. When selecting xenon lights, avoid bulbs with excessively high power, as they can overload the wiring and battery, potentially damaging the electrical system and shortening the battery's lifespan.
