Switch off car engine at neutral or parking station and wait until the engine and lamp are cooled down. Then open the car bonnet.
2. Dismantling Lamp Assembly
Push aside bolts at both sides of lamps, dismantle lamp assembly.
3. Drilling of waterproof and dustproof cover and ring (if necessary)
Check if there is any waterproof and dustproof cover or ring. If yes, drill a proper hole in proper position of cover. Put the HID lamp cable through this hole. Make sure the waterproof and dustproof cover and ring are tightly fixed.
4. Installation of HID bulb
Loose the clamp spring and remove the halogen bulb. Put the HID bulb in the right position inside the lamp assembly. If necessary, lamp holder should be adjusted.
5. Installation of ballast
Choose proper position to fix the ballast according to the rooms available inside the car bonnet. Keep away from hot parts such as, hot water pipe or radiator etc. Use bracket or adhesive tape to fix in the selected location.
6. Wiring
Connect the cable to car battery. Red terminal links to battery anode while black terminal to cathode. Bundle the cables in such a way that they are freely connected to the lamp but meanwhile, keep further away from hot parts. Make sure the wiring is safe and look neat.
7. Installation of lamp assembly
Connect the ballast to the lamp assembly and make sure they are in right wiring (see wiring diagram in below). Then fix lamp assembly.
8. Lighting up and testing

Separating the lamp holder from lamp body. Rotating lamp holder anticlockwise until hear "click" sound. Do not rotate forcefully to avoid bulb damaging.

After fixing lamp holder in the assembly, rotate lamp body clockwise until hear "click" sound to make sure it is firmly fixed. Do not rotate forcefully to avoid bulb damaging.

Installation Troubleshooting
1. Both lamps does not work properly
If both lamps are flash or do not light up, check if the polarity is correct by means of multimeter.
2. One bulb is flash or does not work
Shut off power, changeover the workable bulb or ballast with another unworkable (flash) bulb or ballast to see which one goes wrong, bulb, ballast or cable.
3. Light scattering
Firstly check if the lamp holder is mounted in proper position for the lamp holder is different basing on different vehicle model. Then check if clamp spring of lamp holder reached the designated position.
4. Lamp focus changing (applicable only for Hi/Lo bulb)
Firstly switch off power and remove the bulb. Switch on power again and see whether it can change focus. If yes, the clamp spring of headlight assembly is probably too tight. Loose the clamp spring outward by means of hand or sharp nose pliers such that it would not get stuck.
5. Light flash or discharge
Firstly check whether top part of the bulb is in contact with the hood inside the assembly, or whether it is too close for discharging. In case it is too close, remove the hood inside the assembly. This would not affect normal operation.
