Bests & Worsts Reviews from Amazon

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.
