Passenger side HID Ballast keep blowing
 

Ok so as the topic says I have had 3 ballast blow on the passenger side of my vehicle. The HID were installed for about 3 months no issues and then randomly this month they hate me.

To try to give as much info as I can the passenger side light went out I switched the ballast and the passenger side worked and the drivers side did not. I put a new ballast on the passenger side and that one blew. Did the same thing to check bulbs were fine. Got a 3rd ballast I switch the lights to see if the drivers side would blow. The passenger side blew again.

This all happen within 2 days of installing the new ballast and I had 0 problems for 3 months before that. Also I used 2 different HID sets the 3rd time I used a different HID

What else can it be than bad installation then?

3rd Time I didnt install them. Plus the fact they worked fine for 3 months no issues

You didn't mention where you purchased the HID kit from.
