Why do my hid bulbs flicker or strobe?

Reason #1:

You may require a special harness because your car is not designed to have HID lights32 installed. This is caused by the amount of resistance that is required for the vehicle's electrical system, and since HID is a low resistance and high output application, the vehicle will not send a constant amount of power to the ballasts and cause the lights to flicker and make an error light to show in the dashboard of the vehicle.

Reason #2:

Your vehicle may have what is called DRL, or Daytime Running Lights. This is an option that only works with halogen bulbs because the vehicle's computer only sends roughly 20 watts of power to the headlights and HID requires a minimum of 35 watts of power to the ballasts to ignite the bulbs.

Reason #3:

Check your fuse box. Are your headlights using a 10amp for 15amp fuse? If so upgrade to a 20amp fuse. HID lights are best run with a 20amp fuse because the amount of resistance is reduced and the amount of power is increased, also because it is a small increase of power it is still safe for your factory wiring.

Reason #4:

Check your connections! Are all your connections clean and dry? Look inside the connectors, are the pins bent? Was it difficult to connect any of the plugs? This is typically the most common fault in a system, if the connection pins are bent or not securely in place or may even be wet. Also you may have the wires reversed, use a test light to make sure you have the wiring: positive to positive and negative to negative.

Reason #5:

You may not be getting enough power to your headlights to power the ballasts. If you have a volt meter or a way to check the amount of power coming from your headlight connection, you should have at least 7 volts coming from your headlight Pluto power the ballasts. If you do not you may require a battery relay kit.

Reason #6:

Maybe the product is defective, if you have done the previous steps and still have a problem than it is possible your product may be defective.

How to solve HID flickering problem?

To work properly, xenon high intensity discharge headlights require the vehicle?s direct current power to be converted to high voltage alternating current. This is accomplished through a ballast, which provides a voltage to the headlamps when they are switched on. A common cause of flickering HID headlights is voltage that is too low being sent to the ballast.

Causes of Low Voltage

Low voltage in your vehicle?s electrical system can be caused by a defective battery, a poorly performing alternator or the use of daytime running lights. In addition, some newer vehicles have sensors that activate by sending a low voltage to the headlights when they are turned off.

Using a Relay Harness

A relay harness allows the ballast to draw electricity from the vehicle battery directly, which eliminates low voltage issues. In some cases, a capacitor is needed to work together with the relay harness to ensure proper voltage is applied to the ballast.

Incorporating High-Power Capacitors

High-power capacitors allow increased power to reach the ballast, which will then feed the proper voltage to the headlights. This is the most common fix for flickering HID lights and often solves other problems, such as eliminating the ?headlights out? indicator on your dashboard display.i would recommend 4700uf 25v polarised capacitors.

Installing Resistor Packs

Using a resistor pack will cause the vehicle?s electrical system to send the same voltage to the xenon lamps as it would if halogen bulbs were installed.

troubleshooting
1) check all connections for looseness, tighten any connection that is loose.Check the connection to his ballast for sure, connection to his battery terminals and to the signal wire, relay connection etc.
2) Make sure none of the wires insulated jackets have been cut/spliced and wires are grounding out anywhere to the body of the car
3)make sure theres no tension in the wires that are connected into the ballasts, signal, etc give them a bit of slack.
4) check ballast mounting position, sometimes the way you mount it, it takes just as much movement as the car when hitting bumps and such
5) if you touched the bulb, sometimes it will flicker before it fully dies
6) make sure bulb is mounted securely with no play
7) is you even sure its flickering? because if his headlight is loose, or the bulb has play mounted inside the headlight, when u hit a pothole you will see the light is moving up and down, is he confusing that for flickering?
Solution
1) buy a pair of warning cancellers. warning canceller are capacitors that keep energy and give the energy to the ballast when the ballast is in need.
2) buy a relay harness . the relay harness get the kit plug directly to the battery to guarantee a straight 12v.
3) buy a new hid conversion kit with canbus ballast. canbus ballast is the only ballast on the market with built in warning canceller and anti-flickering. its guarantee that you wont have any flickering problem or lamp out error on your dash. It is the last technology of ballast.
