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

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

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 during
the 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 is
difficult 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.
