How Long Do Car Halogen Lights Last?

[Christopher]

Car halogen headlights typically last about 4 to 6 years, with a theoretical cumulative usage time of around 300 hours. If you drive at night three times a week, this would be their lifespan. However, this depends on the frequency of nighttime driving and the duration of headlight use (day or night). Disadvantages: The biggest drawback of halogen lights is their relatively low brightness, which may not meet the needs of drivers who require high-intensity lighting. Their main advantage is their affordability and good light penetration. Halogen Bulbs: Halogen bulbs are the most common type in cars, operating on the same principle as the incandescent bulbs previously used in homes. The bulb contains iodine and bromine gases along with a tungsten filament. When electrically heated, the tungsten filament glows, emitting light. During heating, tungsten sublimates and reacts with the iodine and bromine gases. Upon cooling, the tungsten re-solidifies onto the filament, preventing premature breakage of the tungsten filament.
