Xenon headlights use supporting electronic ballasts to instantly increase the 12V voltage of the car battery to a trigger voltage above 23KV, ionize the xenon in the xenon headlights to form an arc discharge and make it emit light stably, providing a stable car headlight lighting system. According to the authoritative definition of car2100, a xenon lamp refers to a high-pressure gas discharge lamp that is filled with a mixture of rare gases including xenon. The light-emitting principle is that an electric arc is formed between the two electrodes through a starter and an electronic ballast and emits light, which is also called "artificial little sun".
