    So after reading lots of posts here I dutifully ordered a Phillips D4R bulb. I watched Youtube videos and finally took the plunge. Turns out the bulb in my 2007 drivers side is a HB2 9003 bulb which is cheap. Also was real easy to get out. Could be a replacement housing (looked newer than the other one when I bought it). But......Now I'm seeing other posts here where people have used this bulb on 07s,08,s etc. Am I in the "upside down" here? Like,an alternative universe.? Which friggin bulb SHOULD it be????? Obviously I'm buying an HB2 now but......

    The Gen 2 had two different styles of headlights. HID (high intensity discharge) and halogen.


    D4R is for HID headlights. If you have fog lights as original equipment then you should have HID headlights.

    No fog lights = normal halogen headlights

    I think I can help.

    The Gen2 (2004 to 2009) has one bulb in the lower trims and another in the higher trims.

    The D4R HID bulb is used on higher trim levels, while the Halogen 9003 is on lower trim Gen2s.

    The wiring harness is very different, and they do not interchange.

    Thanks. Now I have to try to return the D4 bulb....had a nightmare time with the Amazon supplier. Just to add to my confusion AutoZone database said Sylvania Silverstar 9003 is compatible (no HB2 designation) and O'Reilly said it's not compatible. Gee, don't know why anyone could be confused! Anyway I just finished installing it by hand no tools no bumper removal yes it was very difficult...but doable! Thanks for the info for now my Prius is no longer myopic.

    Owner’s manual lists the bulbs required for your car, BTW.

    As you learned the hard way, auto parts store’s part finder sometimes can be wrong.

    For bulbs, I always reference the bulb maker (ie (Philips); it has always been correct for me.

    Silverstar: Very bright and like most stars does not live long. Excessive heat on the socket too.

    CAREFUL! Early Gen 2 (2004-05) HID bulbs were D2R , not interchangeable with D4R!
