I know I already answered this question, but I will answer it again.. The chime that does the headlights also does it for the Key in the Ignition reminder. Sometimes these small switchs can go bad, and key cylinder lubrication can sometimes fix the problem, but more often than not, the key cyliner has to be replaced. The cheaper route is to just remove the chime box, by following the sound until you find it and unplugging it. However, this will also mean if you leave your headlights on, you wont know...
Check to see if the interior lights are switched "ON" Sometimes they get turned on when you move the headlight switch.
Check the Hazard warning switch
If you turn up your interior dashboard light settings, then the radio display will be brighter too. The radio dims to the setting for the dashboard when the lights are turned on.
pretty easy really, make sure your interior lights are not turned on. Your headlights control should also be the interior light controller. Turn it clockwise or counterclockwise to turn your interior lights off. You'll run your battery down if you dont
You probably turned them on by accident. They are controlled with the same pull switch that turns on the headlights. By twisting the switch to the far left it will click and the dome lights will turn on, by twisting it to the right it will turn off the interior lights and will then dim the dashboard lights.
Perhaps you turned on the interior lights when you were adjusting the headlights?
In a 1997 Lincoln Continental : To the right of your headlight switch in the dash is a ( panel dim ) switch I believe if that is turned all the way up then the interior lights will come on
Turn signal bulbs and hazard bulbs are the same bulb. When the turn signal is turned on, the indicator light on the dash flashes in tune with the turn signal. When the hazard lights are turned on, an extra fuse which is live, powers the hazard flashers, even if the car is turned off.
First thing you want to check is the dimmer switch to see if it is turned all the way down.
On your light switch there is a dimmer for the dash lights . if you turn it all the way to the left your interior lights should come on , turn it to the left and see if that works otherwise it might be a door switch .
Press dome override button 3 or 4 times till you here a beep to put headlights and interior lights back on auto
The dimmer switch when turned just past high, turns on the interior lights. There are switches in the door opening that turns the lights off when the door is closed. Either one of these can cause the lights to stay on if they fail.
