Do I need to replace both headlights if one is broken?

Headlights can be replaced individually, but nowadays it's common to replace the entire headlight assembly, which is a complete unit. If replacing a single headlight, you should consider the issue of color difference, as products from different batches may have color variations. Below is some relevant information: 1. Definition of car headlights: Car headlights, also known as automobile front lights or LED daytime running lights, serve as the 'eyes' of a car. They not only affect the owner's external image but are also crucial for safe driving at night or in bad weather conditions. The use and maintenance of car lights should not be overlooked. 2. Types of car headlights: Car headlights include gas lamps, incandescent lamps, halogen lamps, xenon lamps, LED lamps, and laser headlights.
I also encountered a situation where one of my car's headlights went out before. At that time, I drove straight to the repair shop, and the mechanic said there was no need to replace the whole unit—just replacing the bulb would suffice. It mainly depends on your car model. Regular halogen bulbs are very cheap; you can buy the same model online for just twenty or thirty yuan, and it's not difficult to replace them yourself—just follow the tutorial to unscrew the lamp cover and do it. However, pay attention to the lifespan of the other bulb. If the car has been driven for five or six years, the other bulb is probably nearing its end too, so it might be better to replace both at once to avoid repeated hassle. Last time, I only replaced one, and three months later the other one burned out, making multiple trips to the repair shop even more troublesome. When choosing bulbs, pay attention to matching the color temperature and wattage to avoid a significant difference in brightness between the two sides.
