    Passenger side headlight works normally on both high and low beam.

    Driver side on both high and low beam are flickering. The flickering is not
    random, but is more consistent, like a strobe light.

    Any ideas?

    Since the passenger side light works normally, I would think that the relay is
    not the problem.

    Do you have HID? Are you talking about Gen 2? Your profile shows gen 3.

    You’re sure it’s not HID? Just replace the H4 bulb then.

    Sounds like it's HID.

    Well, you are right it is HID.

    I have the bulb out now.

    Is a rapid ,strobe like, flickering most likely caused by a bad bulb? Or is some other component
    of the HID system likely to be whats causing the problem?

    For some reason I thought 2006 was the first year for HID in Prius.

    It's most likely either a bad bulb, or a bad ballast.

    Easiest way to find out which is swap the bulbs from side to side (driver's goes to passenger's, etc). If the flickering moves to the passenger side, it's the bulb, if it stays on the driver's side, it's the ballast or wiring/connectors on that side.

    If I had to guess, it's a bad bulb. Replace in pairs if you do need a new bulb.
