Common Issues & FAQ

 

1. The headlight bulbs from my HID kit don't fit where the stock bulbs were...

Some owners make a mistake in assuming that any HID bulbs will fit on any model of vehicle. Double check that you've received the correct HID kit for your vehicle, specific to its model-year. Our site allows you to choose parts specific to your vehicle, though you may need a special adaptor to secure the lights.

2. I'm hearing something unusual after installing the HID bulbs...

Sometimes, immediately after installation, you'll hear a low humming noise after turning on your car's new HID headlights. This is often a normal adjustment. If the noise persists for longer than 10 minutes, or if the noise is more of a clicking sound, pop open the hood and check everything out. Make sure the ballasts and bulbs are properly connected and secured, and make sure everything's receiving the right amount of voltage, according to manufacturer guidelines.

3. My car's HID headlights are flickering...

Again, check the bulbs and the ballast, and make sure everything's been secured properly and connected to the right parts. If your there is an issue with the HIDs receiving adequate voltage, you may need to make some adjustments to your vehicle's voltage output (20 amps is a minimum requirement). Regardless of whether this problem occurs just after installation or later, if you can't find the problem from the checks mentioned above, turn off the headlights and take apart all connections. Using a proper cleaning solution, you need to clean each of the connectors. Reset the HID safety chip, and then wait 5 or so minutes before reconnecting everything. Generally, this problem is a loose connection issue, but blown fuses and harness problems can sometimes also cause the headlights to flicker.

4. Without warning, my vehicle's headlights will just turn off...

To prevent damage to the HID setup, the HID ballast contains a computer chip that can detect issues such as electrical surges, unexpected jumps in voltage, and power deficits. High temperatures can also trigger the chip to react. What the chip does is shut down, entering a sort of safety mode. This usually resets within 3 minutes. If this happens to you, shut down your car's headlights, wait about 5 minutes, and then try starting it again. If the problem persists... pop open the hood of your car. Take a look at all of the connections between the various HID components, and also make sure the vehicle's battery is working properly.

5. I got my car's new headlights to turn on, but soon thereafter they both shut off...

You may have overwhelmed your vehicle's fuses by installing these HID upgrades. You need to make sure you're using 30mA fuses, which should be included in your HID kit. If you're not using them already, equip them, and then try the lights again.

6. The HIDs work fine, but only when the high beams are on...

If you're using an H4 HID kit, the 3-prong setup sometimes causes confusion during installation, as it doesn't work as simply as just hooking up positive and negative wires. Go back the manufacturer's instructions, and simply make sure each wire is connected to its complementing part.

7. What do I do if only one light works and the other doesn't?

Pop open the hood. Make sure all the connections and wires are hooked up properly and aren't damaged in some capacity. If that's not the source of the problem, check the bulb itself for any damage or interference. Still not getting the light to turn on? Check the vehicle's fuses, and make sure they haven't been blown. Remember, a 30mA fuse is required for use with HID components. If the fuses too are in working condition, your last check should be on the igniter and ballast. For situations in which none of these components are the issue, there could be a more severe problem with your car's electrical setup that goes beyond the HID system itself. Test other components on your car to see if only the HIDs are affected, and get your car checked out at the shop, if necessary.

8. Did I do something backwards? My car's new HIDs only work when the engine's off...

On many higher-end and newer vehicles, computer chips regulate headlight function and cut off engine power to aftermarket components. You'll need to bypass the engine and directly connect the HIDs to the vehicle's battery in order to make them work.

9. There's something weird going on with the colors of my HID headlights...

Don't panic. Most of these color problems aren't at all serious. If the issue is that the bulbs are transitioning between colors when they're first started up, it's because the HID ballasts haven't yet reached equilibrium with the battery power they're receiving from your vehicle. Once stabilized, the lights should match the color you selected before making your purchase. If instead the issue is that the colors (or other features) are different between the bulbs, the problem is likely just an adjustment hiccup. After using both HID headlights for several hours after their initial installation, check them again and you'll most likely find they've evened out in color.

10. The HIDs I installed don't work period. Help...

If your car's headlights aren't working at all, it's almost certainly because you inserted the opposite connecter into the ballast. Simply switch them to fix the problem. An occasional issue is that certain cars have wiring that switches polarity, so you'll just need to reverse it to correct the problem. If you try these things and your car's HID still won't turn on, or flicker when they do, recheck all the connections, wires, etc. If you can't find anything, seek out professional advice. The problem may be with the entire HID system, or with your vehicle itself.

11. I think I broke my HID headlights by starting the car with them already on...

You didn't, so don't worry. Most likely you just tripped the safety mode of the chip located inside the HID ballast during ignition. This can cause one or both bulbs to shut down. Once the chip resets, your car's lights should be good to go. Just remember... always start the engine with the headlights shut down, and if you really want to avoid this problem, try equipping your car with a wire relay harness.

12. Something's messed up with my car's high beams now that I have the HID low beams installed...

Often times, this problem results in one of two occurrences. One possible result is that nothing happens at all when you switch from your HID low beams to your car's high beams. Another is that all of the headlights go out when you switch to your car's high beams. Either way, there's no reason to panic. This usually happens as a result of a connector polarity issue. Different car producers use different headlight configurations for high beams/low beams/ground/etc. You'll just need to take some pliers and remove the pins from the connector, which you'll then place into the factory harness in a new configuration. Remember the following color matchups to make things easier on you: ground (brown), low beam (blue), high beam (white). If everything's hooked up correctly now, just take a quick scan over the headlight housing, the headlight lens, and the positioning of the components to make sure everything's in good working shape and facing the right direction.
