Is it necessary to replace halogen bulbs with LED bulbs?
2 Answers
Halogen bulbs can be replaced with LED bulbs, and whether it is necessary to change them can be decided based on the owner's opinion. If you are determined to modify the LED lights, it is essential to go to a 4S shop or a professional auto repair shop and have professionals perform the modification. This is because LED headlights are a systematic project, not just a matter of changing a bulb. If you fail to replace them successfully by yourself, it may cause unnecessary trouble for driving. The basic light-emitting principle of halogen bulbs is the same as that of incandescent bulbs, both of which conduct sufficient current to the tungsten filament to heat it to an incandescent state and emit light. The difference is that the glass shell of halogen bulbs is filled with some halogen element gases, usually iodine or bromine. The presence of these halogen elements can slow down the wear of the tungsten filament at high temperatures, prolong the life of the filament, and also allow the filament to work at higher temperatures, thereby achieving higher brightness, color temperature, and luminous efficiency. Currently, most car headlights are halogen bulbs.
As a driver who frequently drives at night, I think it's necessary to replace halogen lights with LEDs. Halogen lights have low brightness, especially on rainy nights or mountain roads, with short visibility distances, which increases safety risks. After switching to LEDs, the light is brighter and whiter, with a wider illumination range, making it much easier to see road conditions. Halogen lights have a short lifespan, usually burning out within a year, and frequent replacements are troublesome; LEDs can last over ten years, saving both hassle and money. Although the initial cost of LEDs is higher, it's worth it in the long run. During installation, pay attention to compatibility—some older car circuits may require additional resistors for decoding to avoid flickering or error messages. In short, from a safety perspective, the money is well spent, especially if you often drive at night.
