Differences Between Genuine and Aftermarket Car Headlights
2 Answers
The following are the differences between genuine and aftermarket headlights: 1. Sealing performance differs: The housing of genuine headlights maintains its sealing performance without degradation; whereas the housing of aftermarket headlights may experience a decline in sealing performance. 2. Price and quality vary: Genuine headlights are relatively cheaper compared to aftermarket ones, hence their quality is slightly inferior. 3. Workmanship differs: Genuine headlights for cars are imprinted with the vehicle's logo, feature fine craftsmanship without flaws or burrs, while aftermarket headlights exhibit poor workmanship with burrs, rough edges, and unclear printing.
I've driven multiple cars and compared the differences between OEM and aftermarket headlights, which are quite significant. OEM parts are produced by the car brand itself, identical to those installed at the factory, with durable materials that resist yellowing or cracking, and provide uniform, stable lighting that can last over five years without issues. Aftermarket lights are much cheaper, costing just a few dozen to a hundred dollars per pair, and are available in various brands, but their quality is inconsistent: some lamp housings turn yellow and fog up after a year, with reduced brightness; others may not fit properly during installation, requiring rework. I once used aftermarket lights on one of my cars, and at night, the scattered light made it hard to see the road, and they were more prone to water ingress during rain. For safety reasons, if you use your car long-term or frequently drive at night, OEM lights, though more expensive, are worth it to avoid potential risks. Aftermarket lights are suitable as temporary replacements or for saving money on older cars, but it's important to choose reputable brands to minimize problems. Ultimately, the difference lies in durability and reliability, and the choice depends on your driving habits and budget.
