Trouble Shooting HIDs

Out of high demand I bring you a simple trouble shooting guide. I answer this question daily: “How do I know if I have a bad ballast or bulb?” I don’t know off the top of my head but I know how to test this in a few easy steps. First and foremost, check all of your connections! Be sure everything is connected properly.

There are only a 3 reasons why your HIDs won’t turn on. They are 1, No Power 2, Bad Ballast, and 3, Bad Bulb. Here is how to tell the what the problem is:

Power: If you just connected your HID kit and they don’t turn on check the power connections. Take note that HID ballasts are polarity sensitive, and are labeled with a small + and – symbol on the power input connector. If you are connecting your HID kit directly to your cars light socket (why risk doing that) the connector may be wired backwards. The Halogen bulbs that you just removed before installing the HID bulbs are NOT polarity sensitive. If you are using an HID Relay Harness be sure to check the ground connections and the battery connections. Ground connections should be free of corrosion and paint. *Note that plastic is not a good source of ground* (try to ground it back to the battery if possible) If the connections check out than you may have a bad relay. Check to see if the relay “clicks” when the lights are turned on. If it does not, check the input connections. If they are good than you could need a new relay.

Ballast or Bulb: If for some reason one of your HID lights stops working refer to the power section above. After you check into the power supply and you verify that there is power and ground at the ballast connections you will now need to check one thing. When you turn on the lights do you hear a buzzing sound from the suspected bad ballast? (this buzzing will last for about 2 seconds and be accompanied by flashes of light from the HID bulb) If this happens you need to try plugging the working ballast from the other side of your car into this side of the car. Does the other working ballast do the same thing? If you answered YES than you have a bad bulb. If you do not hear that buzzing sound than you most likely have a bad ballast.

Hope this helps you diagnose any issues that you may be experiencing. Feel free to email me directly if this does not help. My email is tech@v-leds.com.

    I already have bi-xenons on my 2007 Mini S. I recently purchased the 6K D1S bulb and I noticed poor light output. I plugged them using my OEM wiring. Will the output make a difference if I use the short wiring it came with?
