Prius high beam lights work but low beam lights do not work?

When the lever is turned to the usual low beam "on" position, no lights. The high beams come on when the control lever is depressed.

    W/ or w/o daytime running lights?HID or regular headlamps?

  • Charles Feathers Oct 29, 2012

    I think w/o daytime running lights and the regular headlamps that came with the new car.

    My wife has the car at work so I can't check the drl

  • Charles Feathers Oct 29, 2012

    I downloaded a PDF manual. The daytime running lights are simply the headlights running at reduced brightness even with the lever turned to off when the Hybrid System is on and the parking brake is off. I assume the headlights are regular lamps that came when the car was new.

    I wasn't sure which fuse was a H-LP LO 15A so I pulled all the 15A fuses and they all looked good. I did manage to drop one of them into an irretrievable crevice. I'll buy another tomorrow. Thanks for the suggestion.

    It wasn't the fuse, but it would have helped a novice to mention that the fuse names are listed on the inside of the fuse cover. Also, there is a white fuse removal tool inside the fuse box. I guess I could have looked up the info on Goole.

    What was it? My car is doing the same thing and I am afraid of dropping fuses.

    What did the problem turn out to be? I am afraid of dropping fuses for nothing.

On a 2008 Prius, If both High beams work but only one side has working low beams, then it is most likely a fuse. So before breaking your knuckles to change the bulb, check the fuse first. I found out the hard way as my mom distressed to me that her drivers side headlights were out. So without checking to see if low and high were working, I proceeded to remove and replace the bulb - ouch! There are 4 10 amp fuses that protect the circuits for low/high beam function. They are under the hood in the fuse box on the drivers side and they are marked on the box cover. Check them before changing the bulb.

Just a guess, take a look at the engine room relay box and check the 15A H-LP LO fuses

SOURCE: low beam ok, spotties ok , high beam not working

It sounds like you have a contact problem in the column switch or the high beam relay.

2004 Saturn low beam lights don't work

Saturn what , ION , VUE , L300 LW300 ? Did you check the fuses ? 2.2 l headlamp relay . The lights are controlled by the BCM - body control module .
The headlamps may be turned ON 2 different ways. First, when the driver places the headlamp switch in the HEAD position, for normal operation. Second, with the headlamp switch placed in the AUTO position, during operation in low light conditions.
On vehicles with manual headlamps, the LH HDLP and RH HDLP fuse in the fuse block - underhood, supply battery positive voltage to both low beam lamps and high beam lamps at all times. The low beam and high beam circuits continue through the fuse block - underhood, through the body control module (BCM), and to the headlamp switch. The low beam or high beam circuit then, depending on the position of the dimmer switch, continues through the headlamp switch. When the headlamp switch is placed in the ON position, it provides a ground path for the low beam or high beam lamps through G203. The low beam and high beam circuits are monitored by the BCM.
I don't think this is a fuse problem ! more then likely a headlamp switch or dimmer switch or a ground problem or relay if your vehicle has 2.2l engine !

Headlights wont turn

sounds like the headlight switch is defective and needs replacing,but you need to check to make sure the rod that the switch pushes against if make the full travel and not short as this will not allow the switch to change from low beam to high beam.if the rod is travelling the full length then the switch is no should also hear a click when moving the arm to go from low to high if not then the switch is holding the lever at a certain position to get the high beams to work this also indicates a switch problem.

When I turn on my highbeams, the lowbeams shut off. Is this normal?

Yes, the low beams will shut off if you turn on high beam. Not sure which way yours work but if you push the lever for high beam, pull the lever back and all lights will come on or vise versa. You would think all the lights would turn on when going into high beam.

The headlights are stuck on high beam.

pull on the signal lever toward you (ceter position). the signal lever controls the head lights either high beam or low beam. if you pull on the signal lever toward you again, you will have high beam temporarily. and if you push the signal lever towards the front, you will have the high beam locked.
