HID light flickers, then goes out?!

[GunnerRunner13]

So today I got my HID conversion kit, installed them and everything was good. Then I just tried them out, left them on for a while.. The left one started flickering then went out?
I cant figure out what the problem is. Help?!

Are you using a wiring harness?

Try swapping the ballast or HID burner to the other side to isolate the problem.

A second that.

Also, are you running a relay as well? what brand kit?
