Is it necessary to replace halogen bulbs?

[VonCassandra]

Halogen bulbs do not need to be replaced. Vehicles with modified lighting will not pass the annual inspection, and in the event of an accident, the insurance company will only compensate for the original halogen bulbs or may not compensate at all. The principle of halogen bulbs is to inject halogen gases such as iodine or bromine into the bulb. At high temperatures, the sublimated tungsten filament reacts chemically with the halogen, and the cooled tungsten re-solidifies on the filament, forming a balanced cycle that prevents the filament from breaking prematurely. Precautions for using halogen bulbs: 1. Turn off the power when installing, and use a plastic sleeve to keep the glass shell of the bulb clean. Do not touch it with your hands. If accidentally touched, clean it with alcohol; 2. When the halogen bulb is lit, avoid direct cold air blowing onto the bulb.
