What is the function of halogen lamps?

Halogen lamps can replace the function of incandescent lamps, and they have a longer service life, easier brightness adjustment and control, and better color rendering of light. Because halogen bulbs have high luminous efficacy and great illumination brightness, they are suitable for occasions that require concentrated lighting. Working principle: The principle is to inject 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 will re-solidify on the tungsten filament, forming a balanced cycle and avoiding premature breakage of the tungsten filament. Therefore, halogen bulbs last longer than incandescent lamps. Impact: Many cars use traditional halogen bulbs, and more than 60% of traffic accidents occur at night or in poor weather conditions. The lighting effect of halogen bulbs is greatly reduced at night or in poor weather conditions. At this time, the driver's vision is severely affected, making them prone to fatigue, distraction, etc., and the probability of traffic accidents increases significantly.
Speaking of the role of halogen lights, I think their main function in cars is to provide bright and reliable nighttime illumination. As an average car owner, I rely on them every day for my commute, especially during rainy or foggy conditions, where their strong light penetration helps me clearly see the road and obstacles, avoiding collisions. Compared to older bulb types, halogen lights are more energy-efficient, saving on electricity costs, and have a longer lifespan, typically lasting around two years. Replacing them is quite simple—I’ve done it several times myself without needing specialized tools. Although LED lights are becoming more popular, halogen lights are low-cost and economical, making them particularly friendly for older cars. In short, they enhance driving safety and convenience, serving as an essential assistant in daily driving.
