Sometimes, aftermarket headlights may not perform or fit as they should. This happens if their original design and equipment specifications do not correspond to those of the original equipment manufacturer (OEM).
Designers and engineers from car manufacturing companies work to ensure that all parts follow certain specifications that dictate how parts should function, fit, and appear. As such, OEMs must adhere to the requirements and produce parts with consistent quality.

Aftermarket manufacturers do not receive such instructions. They usually copy how OEM parts look like. Slight differences may arise in their appearance and fitment. In addition, in a race to cut production costs, headlights produced may not be as functional or durable.
The same case may apply for interior light bulbs. Appearance may not be such an important factor here. However, when it comes to performance, use of inferior material to cut costs may lead to weak bulbs that don’t illuminate as they should. In addition, they may not last that long since they don’t adhere to operational requirements. Buyers will notice the difference only when they encounter a problem.
