Check the pin switches at the door(s)
Probable broken wire in the harness in the drivers door jamb.
Flasher stuck in closed position defective switch
The IOD fuse feeds the interior lights, radio, and other interior items.
Try the lightbulb it self, corrosion on the contacts
check the fuse
Defective light switch.
there is no button of switch you have to disconnect the negative battery terminal
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.
I would say 1 of your door switches are bad or your door doesn close all the way.
check for blown fuse. Or check and see if fuse is in all the way.
Fuse connections. The connectors for the dome light in the fuse panel get loose, you can try and bend them back with a small screwdriver to make the connection again.
Check all the door and light switches, they are turned on by twisting the light switch to the left, also the pin switches on the doors will activate the cabin lights.
