Why We Need LED Bulb Canbus Decoder?
Since LED headlights work differently than original halogen lamps, the feedback signal from the LED headlights may not be detected by the on-board computer after replacing the LED bulbs, resulting in an error message on the instrument panel. Therefore, it is necessary to install an LED decoder to solve the fault alarm caused by retrofitting LED headlights.

Built-in powerful can-bus chip, compatible with 95% of on-board computer systems on the market.
The LED canbus decoder has an all-in-one design, just connect the wire with the provided connector, plug and play.

1.May not solve all compatibility issues as every car system will be a little different.
2.Since canbus decoders can get very hot while working, it is best to mount them in a ventilated area and on heat resistant/non-burning metal for longer life.

*DUTIES & TAXES*
It is rare, but occasionally some customers may receive an invoice for duties or tariffs from their home country's customs agency.
The lights do not work properly
1.Check if the power connectors are properly
connected, and make sure that the vehicle headlight
switch is on the "ON" position.
2.Make sure that the vehicle's battery is fully
charged to supply power to the LED bulb.
3.Install the LED bulbs with the resistors (CANbus).
4.The resistor (CANbus) is polarity sensitive. If the
LED bulbs do not function properly after installation,
please reverse the resistor (CANbus) male
connector 180 degrees and try again.
One of the bulbs is not working
1.Make sure the connection is good. If one of the
bulbs still doesn't work, swap the left and right side
bulbs and test again.
2.Some series of car lights are polarity sensitive.If
the LED bulbs do not work properly after installation,
please reverse the connector 180 degrees and try
The lights flicker or flash
Install the LED bulb with the resistors (CANbus) toresolve the issue..
A warning lamp appears on the vehicle's system dashboard.
This is a harmless side-effect of the low-wattage
LED bulbs not being recognized by the vehicle's
system and can be resolved with the installation of
an additional set of resistors (CANbus).
The light pattern is wrong after the car lights are installed
1. Check whether the lamp body is installed and
turned up and down. As H4, H13 and 9004/9007
models are installed separately from the top and the
2. Check whether the lamp body is rotated in the
correct direction and locked in place after inserting
the locking ring.
There is not enough space for installation on the passenger side
For some vehicles, such as Honda CRV 2007-2014,
the headlight assembly on the passenger side is
very close to the fuse box, so there is not enough
space to operate the bulb installation. So we need
unclip and adjust fuse box for easier access duringthe installation process..
Dust cover can not be installed back
For some vehicles, the light housing dust cover can
not be installed back after installing the LED lights.
In this case, you can consult our brand customer
service to request a modified dust cover for free.
The light bulbs isdifficult to rotate in place.
For some vehicles, the light housing dust cover is
thick, which makes it difficult for LED bulbs to rotate
in place in the light housing. To solve this problem,
you need to forcefully push the LED bulbs into the
light housing and then rotate it clockwise.
