Thank you! So cheap compared to 130$ price at the store and the light is great and strong enough. Save me great money. Had them now for 6 months

I purchased this pair of HID bulbs to replace the original bulbs in my 2007 Toyota Prius. These replacement bulbs were an exact fit for the replacement, and provide an excellent quantity and quality of light. One of the bulbs in my Prius was beginning to flicker, which I learned was a sign of impending failure. Considering that my Prius has 98,000+ miles on it without a replacement to-date, I feel very lucky. I learned that the cost of having the bulbs replaced by Toyota could be $500 or more, I was determined to take on the exercise myself.Replacing these bulbs is not something that just anyone should take on... like all other things Prius-related, the amount of space to work in is extremely tight and the process is potentially difficult. However, after studying the tutorials for the process online through YouTube and PriusChat, I felt more than capable. The most effective means to replace the bulbs involves removing the headlamp assembly, which also involves loosening the bumper cover and grille. That sounds like a lot of effort, but now that I know how it's done, I could easily complete the process of removing, replacing the bulb, and reinstalling the headlamp assembly in about 15 minutes per headlamp. If you choose to attempt this, I SERIOUSLY recommend researching and learning about the process first.I chose the 8,000 CRI version of the bulbs to provide the whitest, brightest light, and I'm very happy with my choice even though the do have a blueish tint. The 6,000 CRI version is probably closer to actual daylight. The OEM bulbs are 4,100 CRI, which provides a more yellow, warm light that's just not as effective at lighting the roadway a night. I was completely amazed at how much better I could see after replacing these bulbs.I read a few reviews where people complained that the bulbs burned out shortly after installation. Like halogen bulbs, it is critical that you do not touch the glass portion of the bulb at any time... the oils from your skin will cause the bulb to burn out in short order. When the bulbs arrived, I was happy to see that they were enclosed in a clear plastic container and also had a protective foam sleeve covering the glass portion of the bulb to simplify handling prior to installation. By removing the headlamp assembly to replace the bulb, it was easy to make sure I didn't touch the bulb by mistake during installation. If you attempt installation without removing the headlamp assembly as some instructions state, I think you run a very high risk of damaging the bulb because of the extremely tight space in which you have to work.Time will tell how well these bulbs will endure, but for now I'm a very happy buyer and I've saved hundreds of dollars. I would definitely go this route again in the future if I had to do so.

The bulbs have great brightness. I tried before installing them to see the difference between my old Phillips expensive ones and these. Nice white and brightness. I am waiting to try the one that I have installed at night.My Toyota Prius 2008 has bad space to install them. So, I decided to install the driver side though it took for me awhile as those clips are different than the YouTube videos. I watched so many videos to install it.Finally, the bulbs are great but Prius cars have no space for replacement the headlight bulbs.

The bulbs were cheap but worked great. I no longer have that car. I would buy again from this seller as the lights were bright. Installing the lights in was a breeze.

im happy with that purchase. finnaly I can see normally at night. it fits like an oem part, but don't be fooled installation itself is really hard had to remove bumper it doesnt have to anything with light bulb itself but installation procces can be challenging.

if i could leave one star i would this is the second ones i’ve had the first ones wouldn’t work at all and these ones that i have now work for 30 seconds then stop! DONT BUY!

The headlight makes a bright light with slightly bluish color. They work well and were installed without any problems.

The passenger side headlight went out on my 2008 Prius and I decided I was going to replaced it myself. While looking at the auto stores around me, I quickly discovered just how expensive HID bulbs can be. Luckily, I looked on amazon because they are so much cheaper here. The bulbs came intact and as described. I then had to go on the adventure of replacing the bulb, which any Prius owner knows isn’t the easiest task. I decided to change both sides since I had 2 bulbs anyway. The new bulbs were identical to the ones I took out and once I got to the headlight compartment, went in smoothly. I made sure to use gloves while handling the bulbs since the oils on your hands can mess them up. I will update if there are any problems with them. It’s been a week and they seem to be working just fine.
