The headlights have been going out randomly for the last few months but only one at a time. This evening while driving home from a late meeting, both headlights went out while driving at 55mph. I pulled off the highway and tried turning the car off and on again. Headlights went on when I turned the car back on, so I resumed driving only to have the lights go out again! this time I flicked on the high beams and the lights came on. I stopped to grab a bite to eat figuring I could do the high beam trick again. When I started the car, the lights went on and high beams turned on when I engaged the lever. While driving home, less than 2 miles from where I started the car, headlights went out and the high beams did not work either when I attempted to turn them on. I pulled over to turn the car off and on again but with no luck this time. Very slowly drove the last mile home on the less traveled road with my flashers on...this situation is incredibly dangerous.

Headlights go off by themselves. When I start the car both headlights go on, but after driving a little while the left or right, or sometimes both headlights will shut off.

Headlight and tail lights failed to work at start up, after a while the highbeams did work so car could be driving home. Later that evening everything worked fine at startup.

One week after being at the dealership for its routine oil/vehicle check-up (55,000-60,000), my red brake light, the yellow warning sign and the ABS lights come up on my dashboard. Towed it back to dealership since the brakes didn't work. They found I needed to change my brake actuator and the solenoid that is stuck. According to what I've read, this should not happen period paragraph but if it does it would be on a much older vehicle with a lot more miles with a stop and go history. According to the customer service representative at the dealership this is a malfunction of the part. When I called Toyota they gave me the go around about being out of warranty. I need help. Also there is a reflective line of light that shines on the driver side of the window from my dashboard.

While driving at night, the passenger headlamp assembly (every bulb, not just the main high-intensity bulb) went out. Wiggling the connector at the back of the headlamp assembly when the headlamp gets in this condition does not fix the problem. I can get the assembly back in working condition by turning off the lights and turning them back on again. This is dangerous! when the light came back on again, it was slightly flickering at first and now seems dimmer than the driver side light. I have also had connector-related issues on the rear brake lights, where they go out at random times. Turning the lights on and off does not work to get the brake light working again. I have to manually tighten the connector at the back of the brake light assembly to get the light working again.

I have noticed for some time now allot of Toyota Prius cars driving in dark conditions with no headlights on. The tail lights are on but no headlights. This would suggest to me that there is a manual headlight switch or else different parameters for the head and tail lights. As for the reason, I believe to conserve power on the electric batteries. If the driver is in control of the headlights this control should be taken away. It is rare in this day and age for a manual headlamp switch even on the most basic cars, so I believe Toyota was fully aware of what they were doing and what the drivers were likely to do. But yet Toyota made sure they were legally covered with the tail lights. After all if the driver hits a car or pedestrian its the drivers fault but if Toyota Prius cars suddenly start getting rear ended, its Toyota's fault. If the headlamp is not in control of the driver why the difference in timing when they come on? I would suggest again to conserve power and make their cars go farther on electric power at the expense of public safety. I am writing this primarily from a pedestrian point of view because I am a runner and have had a couple of semi close calls because of the headlight issue and one closer call because they are so quiet.

Passenger side headlight goes off intermittently. I noticed it around May 2009, and reported it during my may pre-paid Toyota scheduled maintenance., which was the last one for my plan. Toyota said they found no problem. The incident is noted on my Toyota paperwork.
