You have a wire break in the line somewhere ... where the ignition main wire crosses the area where the headlight main wires are. Chaffing has caused a fusion there. A friend of mine had a Tempo that would start up if you blew the horn. No key necessary.
Headlights run off the battery not the ignition...
If by "dim headlights" you mean low-beams... the bulbs are bad and must be replaced.
It would not be a good idea. First it is illegal, second it can actually cause the computer to over adjust fuel and ignition timing and cause running issues.It would not be a good idea.

ignition coil
sounds like the ignition control module
i think, depending on the year, that problem is caused by a factory defect.
Blinking headlights can be caused by various factors, including issues with the Daytime Running Light (DRL) module. If the DRL module is malfunctioning, it may cause the headlights to blink unexpectedly. However, other factors like faulty wiring, bad bulbs, or a failing switch can also lead to similar symptoms. Proper diagnostic testing is needed to determine the exact cause.
I had water leaking at the base of the windshield on a Ford F-250. It would run down the inner firewall onto a control module causing lights, blower fans and all sorts of wierd things to turn on with no key in the ignition and the vehicle not running.
Probably a stuck solenoid.
the chime would stay on if the keys are in the ignition (but the car turned off) and if the door is ajar to warn that the lights are still on
yes it will also cause them to blink off & on and
If it starts but doesn't stay running after you release the key from the start position, it means your ignition switch is bad. Not a huge expense.
