While driving on the highway at night, the left headlight will go out. I turn the headlight switch off and back on and the left headlight comes on again. However, within a few minutes it goes out again. This happens repeatedly. One time both headlights went off at the same time. I'm reporting this because it is an issue that many Prius driver's have had so seems to be a design problem. This issue has occurred many times and seems to be a permanent problem now.
The hid headlights on my 2008 Toyota Prius touring model have numerous critical safety problems. The headlights go out completely and randomly at any time while driving. I have been thrown into complete blackness on windy country roads. I have had several vehicles swerve to avoid me as I have swerved to avoid cars, trees, curbs, poles etc. Furthermore, the lights are very dim causing further driving difficulty and danger with even worse performance in inclement weather. I have become very anxious and the lights going on and off distract and worry other drivers. It is so bad that I risk my life by driving the car at night.
When driving home on highway just after dark, both headlights went out simultaneously without driver interaction. Headlight switch was still on, untouched. Visibility outward as well as other vehicles seeing me (black Prius at night without lights) severely impaired, could easily have caused an accident. Pulled over and turned headlight switch off, then back on; lights came on bright and immediately dimmed, apparently normal. Checked online and found a number of similar (escalating) occurrences by others, without a recall yet by Toyota. After pulling over and stopping
Constant headlight bulb replacement - serious safety issue - while driving on the highway a headlight bulb will go out; first on one side then the other side. Bulb replacement has occurred every couple of months for several years now. What happens if both headlights go out at the same time"?? I loose time from work to have the replacements done. Why has there been no recall"

This month, when leaving for a trip, I noticed the passenger side headlamp was out. I planned on replacing it when I returned. Upon returning, the headlamp has mysteriously come back on. I researched intermittent headlamp problems with my car and found out many others have had the same issue. I'm now not sure if the problem is the headlamp or some circuit.
Started to have issues with right headlight on 2008 Prius starting in 2013 but was not aware of the class action lawsuit. Finally replaced the bulb 10/14 and spent $200 out of pocket to replace bulbs. I'm frustrated because the same headlight went out just nine months later!
The headlights on my 2008 Toyota Prius are totally unreliable, have been replaced once, and now I find there was a class action lawsuit - and there should be one again. The dealer does not know what to do. They do not know if the bulbs or the headlight mechanism is flawed. The lights flicker, go out (both or each) unexpectedly, and while driving - this is terrifying. Turns out it is a well known problem and NHTSA has not addressed it fully. Most recent was at the dealer 12/17/2015, flickering, going out, and not properly going to brights. The bulbs cost $188/each. Ridiculous.
Driver side head light turns on, then flickers and then goes out. I have been stopped twice. Replaced relay ($75) no differance..this happens when starting the car before even putting in gear
The headlights intermittently, and without warning, go out. This happens every time the lights are turned on. By quickly turning the lights off and then back on, they have thus-far turned back on. They will remain on for up to ten minutes. The turning off happens whether the car is moving ot not.
Left headlight goes out while setting still and while driving. On a ten mile trip the light will go out 6 - 10 times. Turning the light off and back on makes the light to burn again. I have been stopped by the police for this. When I stop I, turn the headlamps off, when they tell me why I was pulled over for I play dumb and they instruct me to turn on my lights and dim them or put on high beam. They are left scratching there head and I'm on my way. This happens every time the vehicle is driven at night. Also happens setting still.
My lights have been going off intermittently for a few months now. I went to the dealership for a 12 V battery issue and a couple of recall items, including the hybrid cooling recall issue and the dealer thought this might fix the issue but it has not. What happens is that at any given moment, each and every day/night, when I am driving one or the other headlight will go out. Occasionally both will go out. The only way this is remedied is when I toggle the light switch off and on. Sometimes it takes 2-3 toggles to get the problem to resolve, the suddenly and again, and again the one or the other lights go out. Apparently this is an issue with Toyota Prius's of my year. This happens every time I drive and there is no rhyme or reason. I happens when I am driving. I have tested it to see if happen over bumps and it does not specifically--it just happens when I am driving and several times over. I am not a mechanic though you don't have to be one to see that this kind of issue is not the bulb, because when the bulbs are working they shine brightly. It has to be some other issue with the functioning of the lighting system. This happens on city streets, on highways and when stationary. It happens when I am going straight and turning. It happens and any and all speeds.
Headlights intermittently flash off with no warning. Can not be repaired. Sometimes both flip off at same time. One goes out (or both) appr. Every 5-10 minutes of driving, or while car is stationary with lights on.
About two years ago, one of my headlights began to cut out without warning. Now, starting 2 months ago, both of my headlights stop working at the same time without warning, I have had 2 near-misses because of this issue, Toyota, my car manufacturer, refuses to do anything to fix this highly dangerous issue, even though over 200,000 Prius owners have reported the problem. Who knows how many other owners out there who have not reported anything?!
Known formally as high-intensity discharge (hid) lights, they either work intermittently ' making nighttime driving a lot more exciting ' or fail entirely......updated 12/03/15 updated 11/17/17
Headlights short out intermittently. Both headlights have gone out, the left has gone out, the right has gone out. If I turn off the lights and flip them back on, they occassionally both come back on, or one comes back on or neither come back on. This is extremely dangerous at night. It has to be electrical. There's no way it's the bulbs, I've owned the car for a year and have blown through many bulbs already. This is getting expensive besides dangerous. This happens on bumpy roads, smooth roads, turning, going straight. I haven't found a certain thing that makes them turn off. This has been happening for a long time, but I can only choose one date below.
While driving in the early morning before sunrise, several times, the headlights turned off suddenly. Frightening while on the highway. Luckily the lights turned back on. This happened at least 5 different times.
Headlights flicker, dim, and eventually go out altogether while driving. I have replaced the 12V battery and it still occurs. Concerned for safety of myself and my family.
