    My headlights are so dim that I thought they weren't on. So, I took my 2007 Prius to the dealer. This is what they say: My Prius needs 2 HID light bulbs & 2 HID bulb blasters for $2,215.00.

    Seriously? These are just headlights. And what the flip is a "bulb blaster" anyway?

    Are there cheaper alternatives? I am not a mechanic and therefore I will not be able to change the lights myself.

    Any body shop or mechanic can swap them out for a set of halogens. They won't be as nice as your HIDs, but a least you'll be able to drive at night. If the surface is just fogged and/or pitted up - that can be polished out to restore it. Most shops can do that too. Sam's club wanted $35 a few years ago to do my old GMC. Similar fogging and pitting. Beware; the re-polish job will only last a few years before they refog again.


    Hope this helps....

    The Ballasts and bulbs can be purchased online for $100-ish and take an hour or two to put them in... However, LED upgrade bulbs eliminate the need for the ballast which are unreliable to say the least.

    Also, most 2007 Prius need a headlight polishing kit $30 and 1/2 hour of work to make them look like brand new again.

    As for the jerk claiming to charge you $2K, I wish people who tried to rob customers like this knew they were risking jail time for this. Of course in our backwards society they probably get promoted.

    No, the plastic lenses aren't fogged (due to the normal abrasion and/or deterioration of plastic). The plastic lenses are clear. I wouldn't have gone to the dealer for that - unless, maybe I wanted to have the entire assembly replaced. The headlight are on.

    It's an electrical issue - either the HIDs are exhausted and/or the power supply has an issue. The Dealer has already diagnosed and said 1) the HIDs need replacing and 2) I need "HID bulb blasters"

    Apparently "bulb blaster" is the term they use for "inverter" - which is really just a power supply. So, there you have it.

    All that said - I'll have to look into converting these to halogen.

    Dealerships are warranty specialists not experts at diagnostics... They have a well established history of replacing expensive parts to see if it fixes it, rather than confirming the source of the problem first... If it turns out the bulbs and ballasts don't fix it they'll think of other stuff to replace and no chance on getting a refund for replacing parts that didn't need to be replaced.

    I would totally agree with that statement.

    Why not just get a $60 set of HID bulbs and put them in? How long have the current bulbs been installed? Odds are pretty slim that both ballasts (not blasters) went bad at the same time. The ballasts just don't fail very often. Maybe I've just been lucky that every Gen 2 HID model I've worked on that had headlight problems was fixed just by installing new bulbs. And if you do, replace both, not just one!

    I don't repair stuff. The car has had the same headlights since it was new - in 2007.

    Seems like they're replacing everything - both HIDs bulbs and the so called "blasters" - which just sounds like the power supply (or inverter). As for ballasts - that could be an iron core inductor (like those found in old fluorescent tubes) - but, I believe there are electronic versions of those these days (that aren't so heavy or physically large - and probably cheaper). The inductor simply smooths out the current - as well as limiting the current. I would think the ballast would be integrated in with the power supply in one unit.

    Actually, they just sent me an estimate of about $8,300. I'm unsure if that included the oil change that I asked for this morning or replacing the blown out tail lights that I pointed out them when dropping the car off.

    Dealers just bilk it to you until you get worn out to the point of buying a new car.

    EDIT: any links above were not added by me. At this moment "tail lights" seems to be a link to Walmart. I didn't insert this link and I cannot remove the link either. I'm guessing this forum adds these links for revenue.

    If the headlamp shell itself is good, I'd go with @Tombukt2 recommendations. Unplug the power to the ballast, plug in the pigtail connector, snap the bulb in. It's as simple as that.
    Tail lamp bulbs are almost as simple, if there's access doors - so you don't have to rip the interior apart to replace bulbs. I'm sure there's a YouTube video on how to do this.

    Good Luck...

    FWIW, these issues are usually either the bulb or ballast. I ripped out the HIDs on my GMC because I kept blowing the ballast. They kept taking turns blowing. Right side went out, then a few months later the left would go. Replaced with LED's 3 years ago. No more issues.

    I'm guessing there might be a shop capable of making what amounts to a modification. To be honest - I'm leaning more toward just paying the dealer the $2,700 for the oil change and headlight change. Yeah, the money for this is just maddening - but, I don't really have the time to dick around with stuff like this. Fix it - fix it right - and be done with it.

    Yeah, this is one thing I like about having the dealer fix stuff - it's their problem - not mine.

    I did see a couple of YouTube videos on replacing the headlights on a Gen 2 Prius. One guy got the wrong bulbs and it didn't work. Seems like it's a serious pain to remove all that stuff just to get to the HID bulb itself. I didn't stumble upon a video showing power supply replacement - that is to say I didn't happen to see a video of someone replacing the power supply feeding the HIDs.

    In my case it's probably just the HIDs that are weak/bad. These are 18 years old.

    Yeah you've been lucky... I've seen so many failed ballasts in Gen2 Prius that once people are replacing their 3rd and 4th set they convert to LED or Halogen.

    You do not need to be a mechanic to replace a light bulb.

    Also dont go anywhere talking about a blaster, Im serious about this.

    They will try and charge you a crazy price for a "blaster" too.

    You have two pieces, the HID bulb and the ballast.

    Very simple to do but honestly the price they were charging you included the entire headlight assembly left and right not just bulbs and a "blaster" (ballast)

    that's why they are called stealerships and for things like this the dealer is not always the first choice. It's a known issue that these HID fail all the time in gen2 Prius and that estimate is highway robbery! LED conversion is the way to go.

    It's time to find an independent shop to do your 2007 Prius work. For this work any shop with a good reputation, small or large could do this and save you $1500 or more just on the lights.

    It is not necessary to retrofit hid; there are aftermarket (Denso) ballasts for $79 each and hid bulbs for $49 a pair. Total about $210 and direct plug and play.

    Headlight Experts Denso D24D OEM New Replacement Ballast

    It is true accessing gen2 headlights is tricky but not more than an hour's labor.

    It's easier with the gen2 tail lights. All functions except the brake lights are standard incandescent and easily changed. The brake lights are led and are integrated into the "combination light" assembly, but those assemblies are available everywhere for less than $100.

    See attachments for hid headlight parts and supplier phone number.

    I would imagine there is a specialized power supply to drive the HID bulbs. For one you'd need to generate an arc to get the bulbs to start - this could be achieved using a high voltage potential. Heat could also be used to ionize the gas to start the arc - like the do with fluorescent tubes.

    Once the arc begins the voltage will collapse across the tube and the current should be held constant. The series inductor, or ballast, keeps the current relatively constant and maintains that arc.

    All of that aside - I've already paid for new "blasters" as prescribed by the dealership. However, I give it good odds I only needed the HID bulbs replaced. We will never know at this point.

    I'm a day late and $2000 short. :( Ideally I would have found a mechanic willing to go this route.
