l installed aftermarket hid bulbs on my Infiniti G35. Using the stock ballast and harness but different bulbs *8000k*. l had it for about 6 months working fine and now the passenger side bulb will flicker when engine starts and turn off but the driver side is ok. Can you give me any advice to resolve this situation.
Thanks for your time.

Use a ballast made for your bulbs. l wonder if the stock bulbs will still work, or did you wreck the ballast with too much draw?

l think you have a higher (higher than the standard) lumen bulb, and it will produce more heat. Make sure nothing melted in there. Some headlamp enclosures can not handle that much heat. Check the wires to see if any of the insulation melted/burned.

You can swap the bulbs. Put the left one in the right, and the right one in the left. See where the bulb flickers. That will give you and idea if it is the bulb or the ballast.

That is what happens when you only do half the conversion.

It could be the bulb

check out g35driver.com. Headlight problems are common it seems and you will probably find your answer on there.

l do not know much about ur problem--but l would suggest using xenon lights. They r brighter from ur point of view but actually bother incoming traffic less than HID's. They r also a nicer & better color for visibility; many say they r blue but they r not those ugly ass extremely blue lights, they r very slightly blue but they r actually closer to being true white light than normal headlights which r even more yellow than xenons r blue. You will see better & so will everyone else.
