i just realize that my passenger side lights are dim and yellow than my right side which is bright white.

i have HID 6k. I had them set for about 2 years now i was wondering if its the bulb that is giving up or the ballast. Before my driver side ballast gave up on me so i replace it with the mobilehid ballast

The driver side has a MOBILEHID ballast and the left is a different non brand name.

planning to order some new ones if its the problem from HIDXTRA


thanks

 

take the passenger side ballast and try it on the drivers side see if that solve the issue to make sure its not the bulbs itself which most likey happens...cause if the ballast was bad the light wouldnt power on at all...do you have a relay or is it plug into your stock power

 

Yes, try switching sides. Its very possible that one of the ballasts is underdriving or overdriving the bulb compared to the other, as the internal tranformer and mosfet power transistors can wear out over time, accounting for the color difference, the only way to see if its a bulb or ballast issue it to switch sides and see.
