The indicator lights on the control panel won't go out the low oil light is on, low coolant light, emergency brake light, battery light, and tail light bulbs light is on to indicate these things need to be taken care of or repaired, but ALL of these things are in working order no low oil or coolant just bought a new battery on March and replaced the alternator. Now the battery went down charged it back up car starts and runs fine but lights stay on. Car drives fine but lights stay on. Checked everything none of the lights go out but car runs fine.

This can happen when there is a problem with the charging system for any reason. It could be a bad alternator or something else in the alternator circuit. It will require some testing.
