I have an aftermarket 6000K HID installed in my 02 ext for over a year now. I just started the truck today and the passenger side headlight is doing some funky things. It either turns RED instead of the xenon blue, or it just flickers in blue then turns off, Does anyone know what is wrong?

It sounds like the bulb is going bad, what make of bulbs are you using? The cheaper bulbs only lasted me about a year.
