Bi-Xenon HID kits are HID kits that use one single light bulb for both high and low beam headlights. In general, Bi-Xenon HID kits are either H4(also known as 9003 or HB2), H13 (also known as 9008), 9004 (also known as HB1) or 9007 (also known as HB5). Different bulb size has different pin pattern that connects to your high beam, low beam and ground.
One common problem is the HID might have a different pin pattern comparing to your vehicle, if you install the HID kit without modification, you are going to use high beam for low beam and low beam for high beam. If this is the situation, you will experience a problem that your low beam work, but when you switch to your high beam, either there is no change or the HID is totally off. If this is the situation you are experiencing right now, please read on for the solution.
First of all, here is a polarity diagram for H4/9003/HB2:
Here is a polarity diagram for H13/9008:
And here is a diagram for 9004 and 9007 plugs:
If your high beam turns on for your low beam on your HID kit, or if on your vehicle, your lights seem to be acting wrong: This is a common problem associated with polarity from the HID kits connector. Each vehicle manufactures uses a different configuration for (Ground / Low Beam / High Beam). You can easily swap the pins on the hid connector. Here is how you do it. Stick your finger inside the plug where the pins are and bend them down toward the CURVED surface of the plug. Then raise them up a bit and pull from the back. This is the easiest way to swap the pins.
