1998 Lumina lights don't work at night!The lights work during the day but not at night. Does anyone know how to fix it?


Theres a sensor in the middle of the dash by the front windshield that detects sunlight and triggers the automatic headlights. The main headlights and daytime running lights might be on a different circuit, in which case they daytime running lamps would turn off at night and the main headlights would turn on, indicating the main headlights arent working and the daytime running lamps are working as intended.

I would check all the fuses related to headlights, check the bulbs and check the switch, then last the light sensor on the dash.

Head lilghts only come on in the day, not at night. Only my parking (amber) lights come on.


During the day, those are your DRT(daytime running lights). Which says to me, your lights work. Check your headlight switch.

My 2000 Toyota Corolla headlights will not turn on during the night, and stay on during the day


Your Corolla has daytime running lights (DRLs). A photocell determines whether it is day or night. Your DRLs turn on automatically in daytime without you operating the light control ("headlight") switch. Your DRLs are actually your headlights on low beam. At night, the photocell senses it is dark and disables the DRLs. When you set the light control ("headlight") switch to HEAD, the head relay closes and the headlights should turn on. Since they don't, I suggest opening the engine room junction block and checking the 40A MAIN fuse and the 10A LEFT HEAD (UPPER) and RIGHT HEAD (UPPER) fuses. In engine room relay block 5, check the 10A LH-LWR HEAD and RH-LWR HEAD fuses. Replace any blown fuses and the headlights should be working normally again

Can I program the automatic headlights to always shut off when the ignition is shut off - day or night?


I have a 1997 cadillac deville that has both 'daytime running lamps' when put into gear and 'twilight sentinel' which turns the headlamps and parking lamps on at night, and goes off during the day or when it is bright enough.

There is an adjustable delay for the twilight sentinel to turn the headlights off after the ignition key is removed and it is night time.
---
I had the 'daytime running lamps' installed on a 1990 Cadillac Deville that turns the headlamps only on when the ignition key is switched to on with an aftermarket module. The headlamps are about 70% or so as bright as the regular twiilight sentinel headlamps and parking lights and are designed to go on during the day.

The twilight sentinel overrides this feature when it gets dark outside.

I had the daytime running lamps installed by an auto electric shop that specializes in electrical systems, alarms, stereos, etc.

Does this help?

Headlights wont work properly


Sounds like you have a problem in your headlight switch. As far as them staying on sometimes when you shut the car off are you referring to daytime running lamps or the regular headlights? If it's daytime running lamps that like to stay on and your headlights do not like to turn on then there could be a combination of headlight switch and daytime running lamp relay.

It is possible the relay gets the signal from the headlight switch as well, since they generally turn off when you turn your headlights on.

My r/f high beam is out, so I replaced the bulb but I still have no high beam. Also my daytime running lights stopped working, could they possibly be related?


Yes your daytime running light just uses the headlight bulb on a lower voltage so if the headlight is not working the drl will not work as well, they are dirrectly related,,check the head light fuse,and check to make sure the bulb is good,,
