Thank you for your purchase and taking the time to write a product review.
I'm sorry that our products left you a bad impression.
CAN-bus is a Controller Area Network Bus that allows the vehicle’s devices to communicate with each other. LED bulbs draw far less power than stock factory bulbs. The vehicle’s CAN bus system detects the low power draw and determines that the LED bulb is faulty or doesn’t recognize the bulb at all – resulting in the error or flickering.
When such a problem occurs, adding a decoder may solve the problem.
At the same time we are trying our best to improve our products and improve the technology of the built-in decoding of the bulb.
