Both HID bulbs keep flickering
and making clicking noise.
Reason: 1. See whether the HID
bulbs have been connected to the ballasts correctly
and tightly. 2. See whether the batteries of the car
is too old or almost empty. 3. If your car's low beam
has daytime running lights, make sure to disable that
before installing the HID kit.
modules won't fit.
Reason: 1. Inspect if you bought
the appropriate bulb type for your vehicle. Select
your vehicle make on the top left corner to display
the bulb type for your vehicle. 2. Some vehicles
require adaptor that can be custom ordered from us
(ex. BMW E46). Please
HID turns on then both sides go
Reason: It means the fuses are blown. Please check
your fuses box according to your vehicle's user manual
and upgrade the stock 10mA or 15mA headlight fuse to
30mA. The fuses are included in the package. The 30mA
fuses are 100% safe for your vehicle, they won't cause
problems such as damage your other electronic
HID will shut down itself
Reason: Inside of the HID
ballast, there is a micro chip which is used to detect
whether there is any potential problem. Any potential
problems such as sudden high impulse or shortage of
power input from battery or extremely high heat will
trigger the self-protect and shut the ballast off
temporarily. It takes about 3 mins for the micro chip
to reset itself and the ballast will be working again.
Once this happens, please turn off the HID and wait
about 3 to 5 mins.
Inspection Procedure: Please check the car
battery. Check all connections between the bulb,
ballast, & igniter. Check the vehicle battery
light works, although both lights are installed
exactly the same.
Reason: 1. The polarity of one
side might not match with the stock harness. 2. Fuse
might be blown on this side. 3. Malfunctioned parts.
Inspection Procedure: Check all
connections between the bulb, ballast, & igniter.
Check the bulb that does not work. Check the fuses.
Use at least 30mA fuse if the stock 15mA fuse blows.
Switch the failing bulb module to the working one to
see if the problem remains. If the failing light now
works, the bulb may be failed. If the problem still
persists, the Ballast and/or Igniter may be
malfunctioned. Check the Ballast and Igniter, switch
it to the working side of the vehicle. If the problem
still persists, the Ballast and/or Igniter is
malfunctioned. If HID system works properly, your
vehicle connections, battery, alternator, etc. may
The ballasts make electric noise
when first turn on.
Reason: This is very normal, the ballasts are
absorbing powers from the battery to start up, that's
why you hear electric noise.
The HID works initially but
starts to flicker sometimes.
Reason: It might be caused by
damage bulbs or ballast.
Procedure: Disconnect all the connectors
immediately. Clean every connector with alcohol. Wait
more than 5 minutes (reset ballast Safety Micro Chip)
then reconnect or reinstall every connector. Then
check all the connection between ballast and factory
harness (Power Source); check all the connection
between igniters and bulbs (yellow silicone
connectors); check your upgraded fuse, they must be
20amp minimum. Remember, every connector have to be
100% well connected to each other. Do not loss mating
or mis-wiring any connections.
HID will only work when the high
beam is turn on.
Reason: This situation mostly
happens H4 kit because it has three pong plug rather
than just "+" and "-". Make sure you have plugged
those three wires correctly to their positions.
Usually the combination is Yellow, Black and Red. For
more details please check installation.
HID works when the engine is
off, but if turning on the engine the HID will turn
Reason: For some newer model cars such as 04 or UP BMW
or 04 or UP Mercedes, the cars have onboard computers
to restrict outsource components such as HID
conversion kit or aftermarket MP3 Players. Therefore,
the only way for such cars to install the HID kit is
to directly plug the HID ballasts to the car's
The HID bulbs changes color when
first turn on.
Reason: This is totally normal. At the beginning, the
ballasts are storing the power from the battery of the
car. Since the power has not been stabilized yet, the
bulbs will might have different colors or even flicker
a little bit. However, as soon as the power is
stabilized by the ballast, the bulbs will become
The colors or lighting effects
of the two bulbs are different.
Reason: 1. The level of the two sizes' headlight
housings are not even, to adjust the headlight
housings, please check
2. For new bulbs, there are chances that the colors
are different for first couple hours of burning. The
color will turn into normal once after that.
Inspection Procedure: Inspect for damage in
the light housing. Clean the lens of the light.
Inspect the positioning of lights to ensure both are
at the same angle to the road
How to make sure the HID kit
will work properly every time.
Tips: 1, turn on the engine first, before turn on the
HID kit. 2, don't turn the HID on and off frequently.
3, don't install the HID ballasts and igniters near
the engine nor anywhere the water can easily get onto.
4, make sure the connectors of the HID kit is
tightened to the stock harness.
One or both light can't ignite initially. Bulb turns
off after the vehicle just starts.
Inspection Procedure: You MUST DISABLE Daytime Running
Light or "Auto Switch-On" functions before the HID
installation, please click here for more information.
HID system requires a steady level of battery voltage
of at least 12V initially. "Auto Switch-On" and
Daytime Running Light functions draws power from the
vehicle battery which causes the HID system to fail to
If you have Daytime Running Light, disconnect the fuse
or wiring of Daytime Running lights only. Please
contact your vehicle dealer/manufacturer for more
If you have "Auto Switch-On" Headlight function,
ensure to switch the function to "Manual Switch-On"
**To avoid further damages, always remember to start
your vehicle before turn on the HID system.**
