    Having some headlight issues in my '07 Prius.

    I have the Phillips HID bulb coming in the mail today. But fear it may be ballast related.

    General question though, is the ballast all contained within the headlight assembly?
    I've quickly glanced on a ballast replacement tutorial and seems doable but wondering if I could save some time and just replace the entire headlight assy (assuming a new ballast is included in that part) and whether that would solve my issue?

    Contemplating in my head the price for a headlight assy vs price of ballast plus having to remove and install.

    its not that hard to do the balast but i did it once and it went out again. i bought a set of morimoto D2R bulbs and matching ballasts and did a little diy retrofit i have yet to have any problems and much cheaper to replace than the OEM.

    The assembly usually will not come with the ballast.

    So you need to buy
    - assembly
    - ballast
    - bulbs

    Yes. The Philips D4R 42406 was an OEM bulb for 2006-2009 gen 2 with HID option.

    Great. and thank you for the follow-up. That's what I want to know. I wanted the similar performance as the stock. Not brighter than the original so I wont blind the opposite driver. I will order now that one in the picture as you recommended. Thank you again.
