Where to Check the Manufacturing Date of Car Headlights?
2 Answers
To read the manufacturing date of car headlights, you can check the stamp on the headlight. The stamp is usually located at the bottom left or bottom right corner of the headlight, and the production date can be directly seen from the stamp. Here is a detailed introduction about car headlights: Introduction: Car headlights, also known as car front lights or car LED daytime running lights, serve as the "eyes" of a car. They not only relate to the external image of the car owner but are also closely linked to safe driving at night or under bad weather conditions. Taillights: Taillights are installed at the rear of the vehicle and are typically red in color. They mainly include red lights used to alert following vehicles and amber lights for indicating direction, as well as reverse lights that assist in observation. Based on their form, taillights can be categorized into independent, combined, and composite types. Precautions for Replacing Headlights: When selecting new headlights, choose the appropriate bulb model based on your vehicle. Also, consider factors such as annual inspections and whether the battery can handle the load. It is best to opt for original factory headlights. Avoid touching the glass shell of the bulb directly with your hands during installation. Even a small amount of oil residue on the glass can shorten the bulb's lifespan and pose a risk of cracking with prolonged use. Compare the illumination intensity when replacing bulbs and adjust it promptly. Methods to Identify Original Factory Headlights: Compared to original factory headlights, aftermarket headlights generally exhibit inconsistent quality. There are often defects in the edge connections, and the engraved logos on the headlights are often unclear. Additionally, aftermarket headlights have inferior manufacturing standards, leading to poor tolerance fits and uneven gaps between the headlight and the car body. The lighting performance of aftermarket headlights is also subpar, with delayed response times and inconsistent brightness between the left and right lights.
I really enjoy studying my car in my spare time, and checking the date of the car headlights is actually quite simple. The date is usually printed on the glass surface or the metal base of the bulb, with small engraved characters resembling a numeric code. When looking for it, open the hood and check the area behind the headlight cover. You can either unscrew the bulb to see or use a flashlight to illuminate the imprint. Common formats like "2312" might indicate that the bulb was produced in December 2023. Why is this important? Knowing the date helps you estimate the bulb's lifespan. If it's too old, it's best to replace it to avoid the danger of sudden failure while driving at night. I always take a quick look during routine maintenance and jot it down in my phone's notes to avoid forgetting. This method is often shared in car enthusiast circles, and it's especially practical for beginners to try.
