Do LED car lights require ballasts to be installed?

[VanKaylee]

The vast majority of vehicle models with LED lights do not require ballasts to be installed. However, in practice, it is still necessary to analyze based on the specific vehicle model. For example, the LED bulbs in the Teana come with an original set of ballasts, so replacing the LED lights requires replacing the ballasts as well. Ballasts are divided into single-unit ballasts and split-type ballasts, and their functions are: 1. They have the performance of a cold start current of less than 6.5A, ensuring fast startup; 2. They feature a wide voltage design, ensuring normal startup under both low and high voltage conditions. LED lights are light-emitting diodes and are an important component of car taillights, high-mounted brake lights, and daytime running lights.
