Headlight driver's side has same problem as passenger side headlight had (November 2008) which is it winks out on occasion. Headlight will turn back on when the headlight switch is turned off and back on again but will go out again. No rhyme or reason as to when it happens. Started to occur at 45,000 miles.

The passenger side headlight turns off intermittently at night. Comes on and goes off randomly, even when on a flat surface or sitting still. Recently I was driving on a dark, winding road and it went out presenting an extremely dangerous condition. According to the discussion boards, this is a very common indication and very expensive remediation item which will prevent many from fixing during out current economic crisis. I am very worried about my wife driving at night in this car don't want my children in it at night. This is a very serious issue in that the driver could hit something resulting in injury to the occupants, or another car could become confused by the headlight failure resulting in an incident. Again, the message boards are loaded with discussion on this item.

Headlights on 2007 Toyota Prius go out and then come back on when the engine is turned off and then back on. Several months ago this happened with the passenger side vehicle and a Toyota dealership repaired this at no cost. Now it is happening with the driver side headlight and a Toyota dealership will not fix this because the warranty is up. The warranty was up on the first headlight but issue was fixed at no charge. This is a safety issue and this is a common complaint.

2007 Toyota Prius with 44,000 miles. Left headlight goes out intermittently. Works again if I turn headlights off and then back on again. Sometimes happens very frequently other times less frequently. When I turn headlights on, the left or drivers side headlight flickers. Toyota dealer confirms there is a problem with my hid headlights they say it is my problem to work out with Toyota corporate.

Headlights shut off randomly after driving about 15 to 30 minutes. Sometimes it's the right sometimes the left sometimes both. I took the car to the dealer to have it repaired. The bulbs were $186 each, the computer sensors were $360 each. I read on line that this is a recurring problem in Prius and some siennas and that it can happen again!

Driver side hid headlight would intermittently turn off & if manually turned off & on again sometimes would turn on again. I didn't realize the car had this problem for some time but when I did, I brought to dealer on 4/30/08 & they could not duplicate concern. Brought back to dealer on 5/7/08 & they kept guessing (they claim ballast$269, bulb$323.95 & labor$85) as to what the problem was. On 5/9/08, I brought to an outside mechanic who changed hid module for $$200 + $250 labor. Now on 3/02/09 I hardly realized light was out intermittently again. Brought to another mechanic on 4/2/09 changed light bulb for $166.95 + $48.74 labor after having to custom fabricate light because bulb ordered according to VIN# from dealer had a different connection. I have a dangerous condition that I'm not sure has been corrected yet after incurring big expenses. I almost got a ticket by a police officer for the light being out.

2007 Toyota Prius headlights continually burnout within 3 months. After reading many-many consumer complaints concerning the headlights continually burning out, I can now add myself to this list. My 2nd light bulb on the same passenger side has burned out. Toyota is obviously having these bulbs made from an inferior supplier! please read all the consumer complaints on the Prius on NHTSA website along with Prius chat websites. 1000's of complaints on these headlights! I want new headlights installed at no cost from Toyota or full reimbursement for the 2 I've already put in the past 3 months!

2007 Toyota Prius headlights failure. Lights flicker on and off during driving. Sometimes go off and stay off, sometimes don't go off for days. I was on the interstate a few nights ago and both lights went out. I slowed down and pulled over and at the same time turned the light switch off and on again and the lights came back on. The lights on the vehicles behind me gave me enough light to pull off the road, but what if there was not a vehicle behind me" the local Toyota dealership states bulbs are blown and quote me a price of $525 and they tell me that blown headlights are not covered under extended warranty. My complaint is that if the headlights were blown, why do they work sometimes. And what if someone's lights fail and they can't see how to get off the highway in time to prevent an accident"

Hid headlights on 2007 Prius have failed intermittently. The problem is corrected when I turn off the headlights and turn them back on. This happens on a random basis and is continuing.

The contact owns a 2007 Toyota Prius. The contact stated that the high intensity (hid) headlights would become inoperable intermittently. The dealer stated that there was a wire defect that caused the shortage in the headlights. The front driver's side headlight was replaced for $400 at the contact's expense. Less than six months later, the passenger side headlight was replaced. In addition, the entire lighting assembly was replaced for $350 at the contact's expense. The VIN was unknown. The failure mileage was 30,000 and current mileage was less than 48,000. Updated 04-17-09 updated 04/21/09.

The front headlights on my 2007 Prius intermittently go out while driving. The problem occurs with both the driver and passenger side headlights. Once the headlights are turned off and back on, the headlights resume working. The issue has occurred for approximately 6 months, beginning around septmber, 2008. The vehicle has almost 44,000 miles, the issue began at approximately 37,000 miles. Toyota dealerships and the corporate case manager have refused to cover the estimated $400 repair under the extended warranty. I have been told I must replicate the problem at the dealership in order to receive an after warranty review for "assistance" with the repair. As the issue is random and intermittent, this will require me to drive to the dealership with one or both headlights out, which creates an unacceptable safety risk. Toyota claims that this is the customer's responsibility to pay for the repair. I maintain that the vehicle is too new and low in mileage to experience headlight issues. This is a defective headlight problem and Toyota refuses to take responsibility for the safety issue.

The front headlights of the 2007 Prius (and from research every model year of the Prius) turn off while driving. Flicking the on/off switch makes them turn back on, but then they turn off again. This is a chronic problem not solved by bulb replacement, headlight unit replacement or fuse replacement. It is a huge safety hazard because it may leave you driving without lights at night and the units should be recalled.

The headlights and taillights on my 2007 Toyota Prius shut off without warning. Sometimes the issue can be corrected by turning the lights off and on again, but not always. While I was recently driving on a two-lane highway with no streetlights, my Prius' headlights/taillights shut off without warning leaving me in the dark with no way to see. I was able to pull off the road, but I consider this a serious safety issue. When I contacted the dealer, they said they would not cover the cost of any repair since headlights are not covered under warranty and my car is no longer under warranty. The service quote was $1,800 which I plan on paying to correct the serious safety issue. Toyota is aware of the issue per their technical service bulletin: T-sb-0030-08 "hid headlight system - diagnostic tips".

The headlight on mine Toyota Prius is intermittent.

2007 Toyota Prius with hid headlights intermittently failing. First one side then the other and then both on a frequent basis. There have been no accidents in my case but there has been one near miss as I was driving down a country road early in the morning when they both suddenly went out. This issue has been discussed for longer then a year on several on-line forums/ boards and yet Toyota has yet to respond. I am a disabled veteran and can't afford the $2000 Toyota is wanting to replace faulty equipment that is less then 3 years old and has a common failure rate.

Headlights have failed 3 times - dealer charges $100 to change the bulbs. Car is still under factory warranty.

In mid-February the driver's side hid (high intensity discharge) light bulb on my 2007 Prius began intermittently going out. It would be on when the car was started then after several minutes it would turn off. When the car was restarted the bulb would come back on, again for a certain number of minutes. Two days after replacing the bulb on March 2 the passenger side headlight began experiencing the same problem. This is a potentially serious safety issue as the headlights work fine when you first start up the car but go out while driving - which could suddenly leave you without headlights at highway speed. This car was bought in July of 2007, so is less than 2 years old. Warranty replacement was denied as the car has >36,000 miles. This appears to be a known and fairly common problem with the Prius: priuschat.com/forums/Prius-technical-discussion/26884-headlight-out.html.
