So past 2 weeks my hid on driver side has changed color from the right..than few days later it would flicker an an be fine..now few days later it turns on an flickers for a second an turns off....now it fires but it doses not turn on.
I'm thinking it's the ballast on it not the bulb.

need any advice.

 

I'm thinking the bulb, since it's started to change color. But to check, just swap passenger bulb over to rule out ballast.

 

why not troubleshoot, by swapping the good side for the bad side?

 

Color shift is textbook bulb issue.
