----Note----
The bulb has built-in Canbus load resistance to avoid error codes or Hyper flash on the vehicle, etc., and is only suitable for 95% of car CANBUS. Note that LED bulbs equipped with Canbus are suitable for more cars than LED bulbs without Canbus! But not for all cars equipped with Canbus!

After installing the bulb, the following may occur:
1. The bulb does not light up or the bulb is on for a while, then it goes out or the bulb flashes.
2. The dashboard displays an error code or the radio is disturbed.
Then you need to add a Canbus decoder to the bulb. If you have any questions, please ask our staff.

If the bulb is installed and the bulb does not work, please use the 12V power supply on the vehicle to connect the bulb directly, you can detect whether the bulb itself is normal and exclude the interference of other factors.
