DMEX (Pair D4R 35W 6000K Xenon Headlight HID Bulbs Replacement 42406 66450 42406WX Car Headlamps

My wife had a headlight go out on her 2009 Prius and I immediately think of the repair bill of a Toyota. There is no simple job on a Gen II Prius because everything is so awkwardly engineered. It's designed for you to want to just bring it in for service. A replacement bulb from Toyota is $150. A pair of replacement D4R bulbs was $30. I think I will take my chances at 10% of the cost.Anyway, I knew these were a different color than what we had in there, so I planned to replace the pair and keep the OEM as an emergency backup in case we lose one along the way. I figured worst comes to worst, I will just try this, return it if it didn't work, and get the OEM bulb.Long story short, the bulbs work fine, look fine, color matches both sides, and everything seems in working order. I will change my review if they go out quickly, but realistically, I just want it to last a year or two before we get a new car anyway.Tip for any Prius owner; it's not TOO bad once you know where everything is. Take off plastic cover that goes over and around the hood release lever. Take off clips and screws for top of front bumper. Turn the wheels for access in both sides, but where the front bumper meets the fender, these is a screw behind the tire shroud. You can take off bolts across the bottom, but I just muscled the shroud to gain access (very bendable plastic). Once you take the front bumper/fender screws out, and the top row of plastic rivets and screws, the top of the front bumper will pop out and it will drop forward enough to access the headlights. There is a top rear screw, one that was previously covered by the top of the front bumper, and then one on the side under the thick black plastic piece where the front bumper snaps into. Once those are out, you should have enough access to pull the lights out, but if you want more, just remove the top two lights with a quarter twist and that will let you tip the light down. I used a towel and just sat it on top of the front bumper. You will then turn the back housing (the big circle) counter clockwise about 1/10th of a turn. It's very tight and you won't feel it losen, but once you turn it a bit, just wiggle it a bit and it will pull off. From there, there is a silver plug on the back of the HID bulb you need to 1/4 turn and pull off. Then you will see a metal clip hold the light in that you need to pop off (pushing down and out), swing it back, and swap the bulbs. DO NOT TOUCH THE GLASS ON THE NEW BULB. It fits directly where the other was with the colored bar attached to the top of the bulb facing the bottom of the headlight housing (it faces the ground when you put it back in place). Put the clip back on to hold the bulb, put the plug back on the bulb and turn it, put the dust cover back on and turn it another 1/10th clockwise, put the headlight back in place (there is a little plastic hook that goes in place near one of the bolts to help you line it back up, screw in the 3 bolts and TEST THE LIGHTS TO MAKE SURE IT WORKS BEFORE YOU PUT THE BUMPER BACK ON. Assuming it's working, put the front bumper back on, screw in the bumper to fender and pup the shroud back in place, and then put the rivets back into the top of the front bumper, put the plastic shroud back with the rest of the rivets (or throw it away because it doesn't serve a purpose anyway), and you are good to go. It took about an hour once I figured it out. It would take probably half an hour if I did it again. It's not bad, but compared to every other car out there, it's clearly a move to make you take it to the shop when it used to be a ~$600 service bill. Bulb prices are too cheap these days not to give it a go.

Works with my 2008 Toyota Prius Touring model.

These are exact HID replacements for original D4R headlight bulbs in our 2008 Toyota Prius, touring edition. I recommend.Longevity is unknown, but if I get more than 2 years, I'll be happy since I now know it's not difficult to replace them again. Original headlight bulbs lasted about 14 years before noticeable fading. I wish I had realized earlier that they were fading. I thought they went from bright to burnt-out. Nope. They fade over time.It took me about 15-20 minutes to install one bulb, about 45 minutes for the whole job and I was moving slowly. These were definitely easier to install than originally anticipated.The Toyota Prius shop which I trust and use for more complicated work (not a dealer) wanted $240 for each installed bulb. I suppose that's because some people are reluctant to try doing this themselves. If you have a somewhat mechanical understanding of how things work and can keep yourself organized - laying out screws in a pattern to indicate where they came out, you can do this.Some YouTube videos suggest trying to replace headlight bulbs without removing the headlight assembly, but this is unnecessarily complicated.I removed the entire headlight assembly for easier access to the lightbulb. It was not necessary to completely remove the bumper. I only needed to make each side loose enough to pull back and access to side screw which holds the headlight assembly.I removed 3 screws on the bottom side of the bumper and one screw from the back of the bumper under the plastic wheel well cover. With the bottom 3 screws out, the plastic wheel well liner can be pulled back enough to give access to the 1 screw which holds the plastic bumper in place. Once the side of the bumper is loose, it easily bends without damage, allowing access the side screw (1 of 3) which holds the headlight assembly in place.Note, before starting procedures which I describe here, you need to remove the top plastic cover which is between the hood and the bumper. Check YouTube videos for a visual explanation.

Install in my 2011 Toyota Vitz RS. Fit perfectly. Bright enough for the price but slightly less than the OEM ones. Nothing you would notice to much unless you compare them side by side. Also the temperature is cooler on these over the OEMs. Overall no issues after a month of use

The only thing that I cannot testify to with these lights is there a longevity. I have only had these lights in for about a week now. They are beautiful and bright. I got the 6000 K bulbs. There is no yellow in the color and really, no blue in the color either. They seem to be just a perfect color of white. Everything that I see with them shows up in vivid natural colors. They are also quite bright and I love that my 16 year old car now looks like it has factory new headlights. Or at least from the light output. As far as installation goes, they are exactly the same as any other standard bulb that you would put in your car. No harder, no worse. If these last as well as other OEM equivalent bulbs, I will definitely be buying these again years down the road when I need to replace them again.
