Automotive Lighting D4R Authentic Xenon HID Headlight Bulb with 4200K Intense White Light, Fits Select High Beam and Low Beam Positions, 1 Pack

I bought these bulbs for my 2008 Prius with HID headlights, and they were a perfect match — they appear identical to the original OEM bulbs. I had previously tried aftermarket options that didn’t last long and would start flickering or randomly shut off. These have been rock solid so far. Installation in a Prius is a bit of a challenge due to tight access, but that’s a car design issue — not a problem with the bulbs themselves. Now that they’re in and working flawlessly, I don’t expect to touch them again for another 300,000 miles. Highly recommend if you want quality and reliability without the headaches of cheaper alternatives.

My old headlamps were constantly being replaced by various repair shops and dealers, then burning out after about a year or so, every time right after the warranty is up. I went through several set (not kidding, like 4 or 5 set in 7 years), which was crazy-making until I finally got fed up and started googling about it (looking for recall program, thinking maybe I had a bad ballast or bad hardware controller board, bad electrical grounding, bad water sealing, etc.) After extensive research I discovered the short life of the previous bulbs was due to a flood of uncontrolled counterfeit lamps in the market. Yes, there are regular counterfeits of this product on the street, reaching dealers and repair shops, despite their mark-up compared to simply buying online. If you've gone through a few of these and have had enough, I suggest you google how to examine any new lamps, and especially your old dead lamps, looking for counterfeits (just be careful not to touch the glass with your fingers, supposedly the oils from your fingers will cause the glass to overheat when the lamps are lit, causing premature failure as well...) These were fairly priced and (the ones I bought here, specifically selecting supplier as Amazon) are not counterfeit. I bought them, compared with the photos and videos about how to detect counterfeits, and they're legit. Then I found a repair shop that would install the bulbs for labor-only cost, which saved like ~$100 or so compared to having them buy their own lamps. That was just a minor plus, compared to eliminating the regularly failing counterfeits. I asked the shop to provide my old lamps when they were done, which I also examined, and yes, exactly as suspected, my old lamps were counterfeits. Gah! Anyhow, the new, legit lamps have been burning bright for years, no new ballast or new controller board needed. Just no more failed lamps.

I bought 2 of the D4R bulbs here at Amazon. My wife's 07 Prius had the original 9 year old HID bulbs in them and for the last 2 years the front right bulb would go off all the time requiring her to turn the lights off and on to get it to come back on. So I figured it was time for me to tackle this. The dealer wanted nearly 500 dollars for bulbs and labor to change them. I got these for less than 100 delivered and decided to try and do it myself. After viewing many youtube videos just to get an idea of how things were taken apart I decided to go at it. Most of these videos had so much camera shaking and cameras pointed at things other than the actual work being done that I had to end up inventing my own method of changing them. But like I said the videos showed the basics. I started with the passenger side bulb and it took me a couple of hours. I then went to the drivers side and that took another hour. I did manage to get both of them changed and everything works great now. I will tell you that although the task may seem impossible, once you actually do it you realize it was not that hard and that if I had to do it again I could probably do it in less than an hour total as opposed to the 3 or 4 hours it took me. Saved a lot of money here. Thanks Amazon for fair pricing on authentic bulbs.

I started hearing the stories from other Prius owners that the HID's were burning out early and sometimes at the same time while driving down the highway (scarey), and at first dealers were charging $800 per bulb (even more scarey). I was hoping mine wouldn't burn out, but guess what :-) I didn't even bother with the dealers, and I checked at Autozone and they wanted $176 each. Wow! I'm impressed that Amazon is almost 1/4 the price of even Autozone. My first HID started going out at 54,000 miles. When they start to go they will go out for awhile, then come back on if you turn off and on the headlamp switch. It might go out one time a week, then it will be one time a day, then multiple times per day. So don't delay, if you have this intermittent issue you might as well get two of these and change them yourself. I bought 1 at a time, I replaced my passenger side first because my driver side didn't have any issues at that time. Seconds after I replaced the passenger side HID, I was standing in front of the Prius testing the new bulb, it looked great and bright, and I was happy, and wouldn't you know it, but the driver side flickered out right then. What timing! My Daughter laughed about that. So I should have just bought 2 of them at the same time and changed them both at the same time. When I pulled out the old HID from my 2008 Prius, and put them side by side with the new HID, they were identical, same numbers, same Philips manufacturer. That was a pleasant surprise. Don't remove the bumper, no matter what anyone tells you. All you need is a small mirror and a flashlight and a screwdriver, search youtube for "How to change your Prius HID bulb in 10 minutes (part 1)". If Jay can change this HID one handed while holding a video camera in the other hand, then anyone can do this. I am 6-3 and have large hands and I was able to do this without removing the bumper. update: April 21, 2015. both HID bulbs are still working 4 years later !! I did have one small issue after I changed the HID bulb myself. The drivers side was always on HIGH beam (annoying to me and to many other drivers). I searched the internet and found nothing about this problem. I finally figured out when I had installed the bulb, I had put the HID bulb ever so slightly at an angle and the high beam / low beam actuator couldn't move all the way. The solution was to re-seat the HID bulb, I un-clicked the HID pulled it out an inch and put it back in straight this time. Problem solved. Update 2: August 2016, 5+ years later, drivers side HID replacement bulb just burned out at 126,000 miles on the 2008 Prius. The replacement bulb lasted 70,000 miles and 5+ years, much longer than the original factory HID. I drive with my headlights on, day and night. Also, the passenger side has flickered out once, at one point both went out (scary), so going to order 2. I will scout around for a cheaper price but just wanted to update how long this one lasted.

My Prius started having intermittent issues with the D4R original bulbs (touring model) at about 54,000 miles. This is a known problem (the subject of a class action suit against Honda) and the usual solution is to replace the bulbs before they fail on a dark night and potentially cause an accident. My problem, unfortunately, was right after the expiration on the lawsuit warranty extension. This price, through Amazon, was far lower than that from a dealer or even from the local auto parts store. The bulbs (it's a good idea to replace both at one time) came on time and so far they seem to work fine. My one concern, and the reason for four rather than five stars, is the packaging. This may be the only time I ever felt that there was not enough package protection. Usually, my irritation is that a product comes so well protected in blister packs or worse that I have to risk destroying it or injuring myself to get at it. This time, each bulb came in a very small box that was not sealed and had a flimsy top already coming open. These bulbs are very high intensity and it is important that nobody touches them without protective gloves (to protect the bulb, not the person!) to avoid getting natural skin oils on the glass. Concerned, I wiped each one with alcohol and let it dry before installing them (with gloves). As I mentioned, the headlights work fine and I hope they last for at least another 50,000 miles. If the packages had even been sealed with a piece of plastic tape I might not have felt the need to clean the bulbs. The Prius is still a great car!

My 2007 Toyota Prius passenger side headlight was going out intermittently. I would have to turn off and on the headlight to make them stay on. Sometimes it would stay on for hours, other times, they would blink out after just a few seconds. I finally got pulled over for driving with a blown headlight. I figured it was time to replace. I went to the dealership and they quoted me $300 dollars PER headlight! They explained to me that they needed to take off the bumper. Do not believe the dealership service counter that says that the bumper needs to be taken off. I started to do a bit of research on the internets and found that it is so incredibly easy to replace the headlight. It took me all of 30 minutes to exchange the passenger side headlight (which is the harder side to replace). Don't pay exorbitant dealer prices for something you can do in about 30 minutes even without previous experience. Youtube "How to change your Prius HID bulb in 10 minutes (part 1)" for instructions on how to change the bulb WITHOUT removing the bumper. As for the bulb, it is a perfect fit and looks great. The light output, when compared to the old bulb, was much higher. The bulb was a bit warmer in color though. That is due to a event called "color shift" it is when the HID bulbs start from a warmer color and change to a cooler white after some time in use. Since they are brand new, the color is warmer than the old bulbs. The packaging was perfect and the item arrived on time and in perfect working order. Don't be afraid to get your hands dirty every once in a while.

Car lights up the sky - just like when it was new. I drive a 2007 Prius that had flickering head lights that would turn back on if I switched them on and off. Upon telling this to my dealer, he said it was the HID lights breathing their last and that he'd be happy to change them for $200. I said no thanks and went home and ordered these up on Amazon. Turns out he was talking $200 PER LIGHT! Well, just go to U-Tube and find someone with a video camera how-to and you'll be in the park. Only tool needed is a screwdriver and some elbow grease. One lesson I learned is that the back cover of the headlight system is hard to get moving (you got to twist it to the right a few inches to get to the sealed headlight. Don't use a crow bar (like I did and break off the fins) just turn it with all your might. Also helps to put on some work gloves. Of course my car is in the North East and subject to the elements, so if you are in the sunbelt you probably won't have the same issues. In any event, the light work great - and in fact were identical to the ones that came out.

Great bulbs, but with these tips you should have an easier time that I did! 1) Go to YouTube and watch both videos by jnet1 (How to change your Prius HID bulb in 10 minutes (Part 1 & 2) and Brian Mathis (How to install a Prius Headlight and How to Remove a Prius Headlight). The reason for watching both is because one gives tips for drivers side and the other gives tips for passenger side, which ARE DIFFERENT based on the surrounding components around them. 2) Use a thin flathead screwdriver to wedge in between the seal on the black dome and wiggle it a bit in several places. This will help the break any sort of "gunk seal" that would otherwise prevent you from removing this part of the unit. I struggled with this for over an hour and I'm a strong handed adult male who couldn't get these to budge without doing this. Just be sure to it gently, you don't want to break anything. 3) Forget clockwise and counter clockwise, just turn the dome toward the drivers side the unlock, toward the passenger side to lock. Much easier to remember and much harder to overthink. 4) Once you get the dome cover off and start to remove the next part I recommend that from here on out, every step simply do and undo with the existing part to get a FEEL for how it's supposed to go. Since the space is somewhat cramped its great practice and I was able to use this method (in addition to watching the videos) without the use of a flashlight or mirror. This is especially useful when it comes to the metal clips. 5) Take note of how the bulb sits in the housing when you pull it out, you will then know exactly what position to put the replacement in! If it seems hard and you're running into a roadblock, just step away for a few minutes, watch the videos again and keep trying. I now laugh at watching people remove the bumper and so on knowing that it can be down much easier and much faster. Good Luck!
