Probably got a loose ground in the circuit somewhere. Loose connections inside the switch are another possibility.

Headlights run off the battery not the ignition...
Because Mitsubishi Eclipse 1996 doesn't have automatic headlights.
Cars don't turn off completely, they run on battery power. The headlight switch needs to be turned off.
The first thing you need to make sure is that your keys are still not in the ignition. You also need to check and make sure you have turned your headlights off.
You can with some vehicles. Consult the drivers manual.
Headlights might stay on in a Honda Odyssey after the engine is turned off because of a courtesy timer. The headlights will stay on for a few seconds after exiting the vehicle so the driver can go into a building at night safely. If the headlights are staying on all the time, check the timer for this feature.
first check to make sure #1 you have the proper bulbs #2 the bulb is in the socket correctly.either of these could cause the circuit to back feed
I have a 2002 Chrysler Sebring convertible. If you turn off the ignition and remove the key while the headlights are on, then turn off the headlights, the headlights will stay on for 30 seconds and turn off. You can avoid this by turning the lights off before you turn off the car or by switching them on and off again.
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.
Did they used to go off with the ignition? On most cars, the headlights will come on at any time by just turning them on. The car does not need to be running or the key turned on.
use your parking brake this answer is in the owners manual
