Hi i just installed new Osram D2R 6000k HID bulbs into my G35 but for some reason one side is brighter then the other. I checked if the bulb by switching the 2 bulbs but it is still on the same side. Does anyone have any clue what is wrong?

 

your headlamps probably need to be leveled.. since the angle of the lights makes a big difference with HID's, esp. brighter ones, they're probably more noticeable than your stock bulbs.

your headlight pattern is suppose to be off a little bit to divert it from oncoming traffic. The level of the drivers side should be lower. So if you really do need to level your lights be sure to notice the level of stock lights. Don't level them out perfectly even. They weren't designed staggered without reason.

 

Thanks i will try that.
