Prius (Gen 2) :: 2004 - Headlights Turn Off Quite Randomly
Nov 24, 2014
2004 Prius. Sometimes, quite randomly, the headlights will turn off. Sometimes its both, sometimes its the left only, and sometimes its the right only. This affects both main and high beams. The dash lights and tail lights may still be on (panicking doesn't give me time to confirm that), but for sure the Nav panel is still lit.
The first time this happened was when I was driving on a mountain road at night in the rain. It now happens almost every night and I have confirmed that it also happens in daytime. Road conditions (bumpy/smooth, wet/dry, dark/well lit) do not seem to be a factor.
At least once while still in my garage, when I started the car the left light was out. I can get the lights to turn back on by turning them off all the way and then back on. Nothing else works. I have replaced the relay for the lights - that didn't change anything.

I'm a proud owner of a 2005 prius which until recently ran flawlessly. For the past 2 mos, one of both of the headlights randomly turn off at nighttime. If I turn the knob off, then back on, they both work.

I have a 2007 Prius with HID lights. A few months ago the drivers side headlight would randomly go out. If I turned the lights off, then immediately back on, sometimes I could get the light to turn back on. Recently the passenger light started doing this as well. I'm wondering if the bulbs are going bad, or is the ballast going bad? Is there an easy way to check?

My van has 90,000 miles. I am having problems with my headlights not turning on, then when they finally turn on, they will go off randomly. My power door locks have also stopped working. Last night, I found my tail light cover has come off. How can I put that back on? Lastly, my heater only works for a minute, then the air is cold.

So after a pretty harsh storm last night I was driving today and my wipers came on. Went to turn them off and nothing. My headlights and turn signals won't work either. When I pull the stalk to turn my high beams on my wipers go off. Parked the car and the dash lights stay on without my key and the wipers randomly go on and off. The blinkers in the rear remain lit with the car off as well. At work right now so nothing came up when I searched briefly but do any of you have any insight as to why my car is possessed? Going to check grounds when I get home.

Just got a 2014 Prius Three. All my precious cars (non-Prius) had an automatic on headlight system, noticed the Prius doesn't. Can I just replace the turn signal lever with one that has the 'auto' feature? Could it possibly be that simple?

I recently purchased an 05 prius pack 4, it has an Auto mode on the headlight switch that does not work. as in the headlights do not turn on in pitch black night... From the searches I have done it appears that the car should not have auto headlights and yet it has the switch... I dont think its canadian because it does not have DRLs... if some models DO have auto headlights then what would cause them to not work.

My car seems to randomly beep when I turn it off. Yes, I noticed it does it if I leave my lights on. It also does it sometimes when my door is open. But not always. The beep is constant until I shut the door. Is there some trick because sometimes I do not hear beeping at all even when I open the door. Do I have to press the button before I open the door or vice versa? My car really does seem to have a mind of it's own with these beeps that are driving me insane.

This afternoon, when my wife went to start my 2001 prius, it was dead. I disconnected the 12V battery (relatively new) and checked the voltage. About 3 volts. So I put a charger on it and hoped. After about 12 hours it seemed to have enough charge to try it, and immediately the headlights turned on. I jumped in the car to turn off the headlights but they wouldn't turn off. I honestly don't know if the switch was in the on position to start with, but it's definitely in the off position now, and the lights are still on. What's going on here?

I just got my 2010 prius with OEM fog lights. I was wondering if there's a mod that I can just turn on my fogs without having to also turn on the headlights.

Anytime I turn the headlights on, the high beams go on too; I cannot switch off the high beams unless I turn off the headlights entirely (I have been driving with the low beams on during the day for the 5 years I have had the car)
I can find no reason for this; I'm inspecting the fuses (with little expectation). The only thing I can think of is the control switch or wiring. I have standard headlamps, not hid.

With the days getting shorter, I have been leaving the lights on when I park the car in my garage, and rely on the auto-shutoff feature instead. However, today I found out (after someone told me several hours later) that my headlights were still on. As far as I know, if I leave the lights on, turn the car off, and lock it, it should turn off within a few minutes, correct (previous experiences seem to indicate this is right)?

How to make the headlights turn on when the windshield wipers are activated?
You must turn on the headlights when it rains, and I don't want to pay for tickets...

I have Prius 2007, base model + package 2 & no upgrades. Not sure if it came with HID. It does not have a fog light.
I parked the car in front of a restaurant and waited. Turned off the headlights while waiting with engine running. Fiddled with the interior panel brightness dial a bit. When I turned on the car again the headlights wouldn't turn on - both of them. Drove home with hi-beam.
Checked the fuses H-LP LO for both RH & LH sides. They seem fine.
Asked wife to turn on/off headlights from stick - I could hear the click in the relay - so DIM relay is ok. With stick knob set to headlights and car running asked for the stick to be pushed to turn on/off high-beam- Could hear the relay engage + high beam on/off.
I looked closely to see if the mirror is moving - no movement. Just found it is possible for the same bulb to be High & low beams when there is no mirror movement with dual filament bulbs.

I never used the headlight before. Last night, I turned on my headlight, All the indicators like MPG indicators, EV,HV modes , etc. disappeared. Of course, it doesn't matter for my driving this PIP.

We have noticed something strange with the dash in our new 2012 Prius. While driving at dusk and turning the headlights on the dash readout can go completely dark. Leaving only the gear selection indicator visible. This can be completely disorienting and dangerous. This happens if the dimmer wheel is set in the lowest position. It will turn back on if the dimmer wheel is moved up from the lowest setting.
I can recreate the issue parked by simply having the headlights on and dimming the switch all the way down. It will shut off the speedometer, MPGmeter, and Hyrbrid indicator screens.

Just got a 2010 Prius model III and discovered that there is no warning system if you turn it off and get out forgetting to turn the headlights off.
Even my 1997 car chimed if I turned it off and opened the door with the lights still on.
Also, if only the parking lights are on there is no symbol on the dash indicating that.

I have searched the Owners Manual, forum and internet about this, but I can't come up with a solution. Perhaps I am not using the correct terminology. I also have an ALLDATA DIY subscription on this vehicle, but I could not find any instance of this occurring to be able to troubleshoot. I though that there might have been a light out somewhere.

My truck is a 2004 F150 XLT, 4.6L 2 wheel drive extended cab
The truck starts fine. With no lights on, heater/ac blower turned off... my turn signals and hazards work as they should.
If I turn on my headlights, I have no turn signals and the indicators on the dash are slightly lit up along with my highbeam indicators. The actual dash lights do not come on.
The blower does not work at all regardless of whether the lights are on or off. Turning the blower on immediately creates the same issue as the lights. (no turn signals, slightly lit up indicators, etc). The blower does not work on any speed. I can hear the duct work changing direction behind the dash as I move the blower selector from dash to windshield to floor, etc. I can also hear the compressor kicking on for the AC.
What I have done: I have checked all the fuses. I have attempted to remove every one of them while running to see if anything shutting off would let the blower kick on. I have unplugged the blower entirely wondering if there was a dead short. I have removed and unplugged the resistor to see if that might be an issue. I have also removed the right side kick panel and checked the ground wire there that runs to the dash. Everything so far seems to be in good order.

I have a 2006 GS300. I have had a few oddball issues with my car (the engine rattle at start up....the water backing up in the floor behind the passenger seat etc.... ) but this one has me baffled. I turn on the headlights and one or both will randomly go out. Sometimes its the left and sometimes its the right. When this problem started, I thought it was the bulbs so I tried changing the bulbs but that didn't work.
When I turn them on, they both come on and then I leave the house and drive for a few miles, then I will notice that one of them goes out, so I turn the lights completely off and then right back on and they both come back on. Then a few minutes later one or the other will go out again. Sometimes they both go out while I am driving, so I need to flick them off and back on. I have no problem with the high beams or the running lights. I don't drive too much at night so it hasn't been a huge hassle, but it is definitely a problem.

When running and turned off, after 5 minutes of being on, the headlights blink on and off randomly. The only way to stop it is holding the brights/blinker/wipers wand back to temporarily engage the brights. Pushing the wand forward to fully engage the brights does not stop the blinking. Not fun for night driving!
