Is it necessary to replace car halogen lamps?

[Dawson]

It is not necessary to replace car halogen lamps. Halogen lamps are a variant of incandescent lamps. Their working principle involves injecting halogen gases such as iodine or bromine into the bulb. At high temperatures, the sublimated tungsten filament chemically reacts with the halogen, and the cooled tungsten re-solidifies on the filament, forming a balanced cycle that prevents premature filament breakage. Precautions for using halogen lamps include: 1. Halogen bulbs operate at very high temperatures; wait until the bulb has fully cooled before opening the headlight to remove the bulb. 2. The glass shell of halogen bulbs is made of quartz material; avoid touching the bulb with hands or a cloth before lighting it, as this may cause the bulb to lose its luster irreversibly. 3. If a halogen bulb gets dirty, it should be cleaned before ignition, using an alcohol-soaked cotton ball for scrubbing.
