What causes the flickering when replacing LED bulbs in Volkswagen?
1 Answers
Volkswagen replacing LED bulbs with flickering when powered on is likely due to induced electricity, as many wires are bundled together in sleeves or placed closely. When one wire is energized, others generate induced electricity, and LEDs can illuminate with very small currents. It is recommended to retrofit xenon lights with bi-xenon projectors to achieve the original xenon mode, which is the optimal solution. Below is relevant information about automotive headlights: 1. The power of original headlights is generally around 55w, with an operating current of approximately 4.5A, while LED lights typically have a power of only 20w-25w. The starting current generally requires 4A-8A for normal startup, and after successful startup, the operating current is only around 1.5-3A. At this point, the vehicle's computer will detect abnormal current. 2. Some vehicles alert through the dashboard, while others automatically shut off. After shutting off, because the vehicle's power switch is already on, the vehicle will relight the bulbs, resulting in the phenomenon of continuous flickering of the vehicle's lights. This situation requires the use of ballasts or decoders.
