The CAN-bus system can be compared to a human’s nervous system, which is used in transmitting messages to the other systems or parts of the body. The miscommunication between the bulb’s electrical system and the car’s computer can cause flickering | KRM Light+ Problems with the CAN-bus systemĪnother factor that can even worsen this miscommunication is the CAN-bus system (Controller Area Network) of modern vehicles. Think of these items as language translators, which will bridge the miscommunication of your LED headlight and vehicle computer. This problem can be solved by using load resistors, LED decoders, warning cancellers, and anti-flicker adaptors, which will be discussed later on.


The electronic frequency and power of LED lights are different from the usual halogen bulbs resulting in flickering issues. When there is a discrepancy between the headlight’s electronic frequency and the car’s computer, it will lead to flickering. There are various reasons for flickering led headlights, but the most common cause is a failed communication between your car’s computer system and the headlight’s electrical system.
