Why does one side of the xenon light need to be switched several times before it lights up?

The reason why one side of the xenon light needs to be switched several times before it lights up is due to an incompatible ballast or electromagnetic interference, which requires decoding at a repair facility. Below is some extended information about xenon lights: Definition: It refers to a high-pressure gas discharge lamp. Xenon lights are heavy metal lamps that fill an ultraviolet-resistant quartz glass tube with various chemical gases, such as inert gases like xenon. Then, through a booster, the vehicle's 12-volt power supply is instantly increased to 23,000 volts. Under high voltage, xenon gas is ionized, producing a light source between the two poles of the power supply. Advantages: They have three times the illumination intensity of ordinary halogen bulbs but consume only two-thirds of the energy. Additionally, xenon bulbs use a light color nearly identical to daylight, creating better visual conditions for drivers. Xenon lighting fixtures provide a wider range of illumination and greater intensity, significantly improving driving safety and comfort.
A few days ago, I encountered a similar situation with my old Mazda - the right HID headlight would only gradually light up after repeatedly switching it on and off several times, which was really annoying. Based on my experience, this is most likely an issue with the ballast, that little box that provides the starting voltage for the bulb. After prolonged use, internal capacitors can age or components may loosen, requiring multiple triggers to start the lamp. It could also be that the bulb itself has reached the end of its lifespan - HID bulbs tend to ignite more slowly after several years of use. Another possibility is poor contact at the wiring connectors, where dust accumulation leads to unstable power supply. When facing such issues, don't delay. First check if the bulb socket connection is tight. If that doesn't solve it, quickly take it to a professional shop to test whether the ballast voltage meets standards. Delaying repairs could lead to sudden light failure while driving at night, which poses significant risks. The repair won't cost too much anyway - safety should always come first.
