HID light issue - Help

[jsbihn]

Hey all.
I bought a set of HID lights from Amazon. I have bought these lights for my other vehicles before.

It seems that somehow this is a reoccuring problem and I am wondering if you can spread some light on it.

It turns out that the lights will light up, but usually one. Then I flick the high beams real quick and the one light will light up too now.

Just wondering what is wrong or what I can do to fix this.
Seems to happen over various vehicles, different headlight sides, and different manufactures of HID headlight kit.

Any help would be great
Thanks
