2005 grand prix gt have hid lights and had to replace the the kit for the low beams it was plug and play the same as the origanl installed by the previous ownernow my drls will not turn off and when in drive they get extremly bright if I pull fuse then I have no tail lights but brake lights and turn signals all work can anyone tell me what and why this happen ? How can I fix this issue ?

1. My HID Kit or LED Kit does not turn on at all. If you install your HID kit or LED kit and they do not turn on you may have a reverse polarity issue. What this means is the power and ground wires of your vehicle's stock harness are reversed.
To reverse polarity on HID headlights, you must rotate the 2-pin oval connector on the HID ballast by 180 degrees in order to reverse the orientation of the plug.
To reverse polarity on LED headlights, you simply rotate the connector which plugs to your vehicle's factory harness by 180 degrees.
This problem is unrelated to the HID kit or LED Kit. It is an issue with the vehicle's factory wiring orientation. Halogen bulbs are not affected by polarity therefore some car manufacturer may have their polarity reversed.
If your HID kit or LED kit still doesn't light up after reversing the polarity, your headlight fuse might be too weak. Upping the fuse by 5 amps might do the trick.
2. My HID Bi-Xenon high beams or low beams are not working or are inverted. This is a similar issue as above, the polarity of the connector's pins are not correctly aligned. Bi-Xenon HID kits have 3 pins on the harness connector for ground, low beam and high beam connections. You will need to release the pins inside the connector and reorder them. You may need several tries to find the proper orientation. Look inside the connector and with a precision screwdriver you can release the pins and reverse the wires.
3. My HID lights are flickering. Flickering usually means the car is unable to supply enough power to the ballast. You can easily test this by connecting the HID kit directly to the car battery. If the kit works, it is a power issue. To resolve this, you will need a wiring harness.
If your car has Daytime Running Lights (DRL) flickering is usually caused by the lower voltage needed to run the DRL at half power. The car's factory harness does not provide enough power to the ballasts. If the flickering is caused by the DRL you will need a wiring harness or have the DRL disabled (this may not be legal in all areas).
Flickering can also be caused by the vehicle's onboard computer failing self-check test due to the new HID kit you just installed. This can easily be corrected with a set of warning cancellers (capacitors).
4. My LED headlights are flickering. LED lights may flicker on some vehicles, this is caused by the vehicle's onboard computer failing self-check test due to the new LED kit you just installed. This can easily be corrected by adding a set of warning cancellers (capacitors) to your setup.
5. My HID kit works sporadically. If only one side turns on from time to time or your lights work inconsistently, you probably have a power issue. You will need a wiring harness to power your HID kit directly from the car's battery.
If you install the wiring harness and still experience intermittent firing, please check your wiring connections. Make sure the power terminal is properly connected to your car battery and that the wiring harness is securely grounded.
6. Only one side is working on my HID kit or LED kit. If one side sometimes doesn't turn on it could be caused by a bad bulb, HID ballast, LED driver or wiring. To help identify which component is defective follow these steps.

1. Swap the ignitors to opposing sides (not applicable for LED kits). If the problem is reversed, you might have a bad ignitor.
   • This step will check if you have a bad ignitor. The ignitor is the black rectangular box that is plugged between the ballast and the bulbs. To perform this test, please swap your ignitors to opposing sides and note what happens to your kit.
2. Swap the HID ballasts or LED drivers to opposing sides. If the problem is reversed, you might have a bad ballast.
   • This step will check if you have a bad HID ballast or LED driver. The HID ballasts or LED drivers are the two metal boxes that came with your kit. To perform this test, please swap your HID ballast or LED driver to opposing sides and note what happens to your kit.
3. Swap the HID or LED bulbs to opposing sides. If the problem is reversed, you might have a bad bulb.
   • This step will check if you have a bad bulb. To perform this test, please swap your bulbs to opposing sides and note what happens to your kit.
4. If none of the above helps, please check for loose connections. If you installed a power relay harness with your HID kit, make sure you have properly grounded the harness.

Retrofitting HIDs into halogen headlight assemblies is ******* and my look bright to you, but they actually cast less light on the road because the reflector isn't designed to focus an HID tube. Their designed to focus a filament.

To wire up an HID kit on the low beams of your Mazda 3 2005, you will need 3-4 things:
1- HID kit (bulbs and ballasts)
2- HID relay (connects your hid kit to your battery)
3- 4700uF capacitor (solves DRL flickering issue)
4- H7 hid bulb adaptor (you can also use the rubber piece that holds the bulb wires as a spacer)


Wiring diagram:

Tips on How to wire up:
1. HID bulb's amp wires connects with the ballast's amp wires. (There's only one way to connect them.)
2. The positive and the negative spade connectors from the hid relay connect with your vehicle's low beam connector, closest to your battery: the driver side. The passenger side low beam connector is not used and should be insulated. You can use electric tape.)
3. Each ballast is connected to one of the relay's clip connector, and it's grounded on each side to your vehicle's body. (One connector for each ballast, one for each side. You can use the screw for the body as a ground.)
4. The red wire(with the inline fuse) in the relay connects to your battery's positive terminal.
5. The capacitor sits on the relay switch. (Google for how to wire the capacitor onto the hid relay switch.) dynoxg image
6. The halogen bulb sits on an adapter. You can safely remove them from each other, and use an H7 hid adapter instead.

I don't know why you would install resistors inline for an HID kit, they should be 'plug and play'-you plug the connector for your halogen lights into the ballast input for the HID kit, then plug in the HID bulb harness/ bulb to the ballast output, install the bulb into the housing-done. Some people have installed relays to the lights because when the HID's 'light off' the use a lot of power until the bulbs warm up, then they actually consume less than a halogen bulb (usually 35 watts HID to 55 or more halogen). I have HID's in a number of cars and don't have relays hooked up on any, just 'plug and play' and I have no issues whatsoever.

Just get the plug and play kit just need a couple of rewiring the lights to the ballast so it can oower up the light bulb....vvisibility it depends on the watts the higher the number the brighter .... longivity depends on the brand some are good and some are bad good luck in choosing a hid

The hi beams when activated will have all headlight on. If you have to hold the swith in to keep them on that means the switch will not click into the locking mode to keep them on for you. Once you pull back the lever you should hear a faint click. That will lock the high beams on. Pull it again and the same click will be heard and that releases the high beams to off

A loose ground wire to the headlight will keep it dim,Or a headlight adjustment will bring the headlight up.If you can have your headlight turned on a garage door or something at night,and then watch as you change your headlights from low beam to high beam which ones are higher.the last thing to verify is that your high beam headlights are not the plastic lens type that turn dull which cuts the light power.

yours is the fifth problem with the hid headlight kit,
have no idea,it may be their problem since people are having trouble.

Upside down L shaped bracket that is bolted to frame just behind headlight assy. Unbolt bracket, lift bracket straight up to unlock headlight assy. Headlight assy should easlier fall forward to replace any of the 3 bulbs

DRL function is built into the body control module. If your car doesn't have DRL, you'll need to do a full reprogramming on the BCM. Not feasible. Plus, adding HID to halogen headlight assembly is a horrible idea and *******.
