Step  1:  Open hood and locate the factory light bulb you are trying to convert. If fog  lights, you may need to pull out your factory fog light housing to access the  back. On some vehicles you can access factory bulbs from the engine bay or from  the wheel wells with your wheels fully turned on direction. Please consult your  owners manual or dealer on how to access your factory light bulbs. In 90% your  bulbs are easily removed without too much trouble. Once your factory light bulb  is removed, you can prepare for the HID bulb insertion.

Step 2: Remove the plastic capsule preinstalled on the HID bulb and insert into your  headlight socket. HID bulbs should fit similar to your factory light bulb, but  the tolerances may be slightly different on certain vehicle models. Bulb  installation will vary from twisting to clamping from the back depending on the  bulb type. Be very gentle with the HID glass portion. Do not touch the glass  with your fingers. If it does end up getting dirty, simply wipe with clean cloth  gently

Notice:  Some vehicle models may require adapters for the bulb to fit into the socket.  These include H7 bulbs. Some parts off of your original headlight may be be  required depending on car model. Example, 9007 light bulbs will require the  reinstallation of the plastic bulb holder adapter. Some BMW/VW/Mercedes/Saab  will require a metal adapter or plastic adapter to hold the bulb in place.

Step 3a:  Once the HID bulb is fixed into place locate the factory connector where the  original halogen bulb was connected to. You will now connect the supplied wire  (may be a plug or 2 metal tips) that you must insert into your factory connector  as shown below. When we say factory connector, this is the connector your  original bulb was feed power with.

If you purchased a Bi-xenon kit, or a kit with relay, your  installation will be a little different than above. See steps 3b or 3c.

Step 3b:  If your kit included a relay you will not use the provided extra wires shown in  Step 3a. that connect ballast to factory headlight plug. Instead the ballast get  connected to the relay as shown below. The relay then will connect to your  factory headlight plug. Some relays will have two plugs one for each side, while  others only one headlight plug. Remember a relay simply gets a signal from your  headlight plug, then allows power to flow directly from your battery.

Step 3c:  If your kit purchased is a bi-xenon kit also known as hi/low (low beam + high  beam HID with movement). This only applies to kits with bulb types 9004 9007 H4  H13 9008. Notice on these kits there will be only 1 headlight plug connector.  One of your headlight connectors may not be used.

Step 4: Before mounting ballast permanently please test the system. Low beam, high beam  and fog light function if it applies to your install. It is best to turn the  vehicle on to test the system as some vehicles do not give full voltage when  vehicle is running only from battery.

Step 5:  Mount the ballasts on any existing bolt or flat surface away from excessive  heat. We do not recommend mounting on top of the radiator or in front or behind  it. Ballasts are electronic devices which excessive heat can ruin. Make certain  the wires with your kit cannot get tangled into the belt line or are resting on  very hot components of the engine.
