What is the lifespan of halogen headlights?

The lifespan of halogen headlights is generally around 2,500 hours. Here is some relevant information about halogen headlights: 1. Definition: Halogen bulbs, also known as halogen lamps or tungsten halogen bulbs, quartz bulbs, are a variant of incandescent lamps. Halogen lights generally have lower brightness; for example, a 55W halogen bulb typically produces just over 1,000 lumens. 2. Working Principle: They operate based on the principle of thermal radiation and incandescence—simply put, when sufficient current passes through the filament, it heats up to incandescence and emits light. However, the lifespan of such incandescent lamps is relatively very short.
Actually, I've gained deep personal experience about halogen headlight lifespan over my decade of driving. Under normal use, they typically last around 500 hours. For daily night commuters, replacement is needed every 2-3 years. The key lies in usage habits - frequent switching really wears out bulbs. As someone constantly entering/exiting underground garages, I replace mine noticeably more often than my neighbor. Humid conditions like rainy weather also shorten lifespan - I remember one time turning on lights right after car wash when they weren't completely dry, and they failed within three months. Severe vibrations from frequent mountain road driving can also reduce longevity. While modern cars prefer LED lights, veteran drivers still appreciate halogen bulbs for being affordable and easy to replace - any roadside shop can handle it for just tens of yuan.
When it comes to the lifespan of halogen headlights, I noticed significant variations while helping a friend repair his car. Theoretically rated for 500 hours, but voltage stability plays a crucial role. Once encountered a case with an aftermarket audio system where the battery kept draining, causing the headlights to burn out in less than half a year. Three daily maintenance tips can extend their lifespan: avoid wiping the lens with a wet cloth (temperature differences may cause cracks), remember to turn off lights before shutting down the engine to reduce cold-start impact, and periodically clean the connectors to prevent oxidation. If the bulb starts yellowing or dimming, it's nearing the end. Although LED lights can last tens of thousands of hours, halogen's light penetration through haze is truly unmatched.
