Engine shuts off when headlights are turned on

Sounds like your alternators dead with the car running take the positive lead off the battery ifbit dies alternator is bad

Any number of problems can shut down an engine; most modern engines are designed to protect themselves by shutting down if something goes out of whack. Generally, the headlights will dim first only if the alternator is bad or the battery is dying, then shortly after that, the car will shut down.
For most other problems, the headlights won't be affected. Since your lights were not affected, I would first look to see if a code was set, then look for a fuel delivery problem, overheating or low oil pressure. Then move on to more esoteric components.

If your delay module is working correctly, you should be able to turn your headlights off first, then shut the engine off and by then, all lights will go off. never need to use my delay unit always shut headlights off then the engine.

U got a BURNED LiGHT SWiTCH, usually they have plastic inside the contactor that selects the switch from dipping/high and turns on ur LiGHTS!
Replace the whole LIGHT SWITCH assembly!
Hope that might help u out!

If you are turning the engine off before turning the headlights off then the headlights(only) will remain on for approximately 1-min. This feature allows you to use the headlights to get to where you want to, such as to your door with some light.
If your are turning your engine off before turning your headlights off, to turn them off - turn the headlights back on and then back off again. The headlights will turn off immediately.
However, if you are NOT turning off the engine before turning off the headlights, then this feature may be malfunctioning in the switch. To remedy this right away use the above procedure - turn back on then back off; until you can replace the malfunctioning switch.
Let me know if this helped, or if you have additional questions or information. Feel free to contact me at FixYa.com!
Again stated: these will normally turn off after 1-min.

you might have a voltage drop are your battery terminal and lugs are cleaned and well tight

If you're trying to shut them off while the engine is running or the key is turned in the ignition you'll need to have the parking brake on.

If you're trying to shut the headlights off when the car is not running, there is a round knob on one side of the steering wheel that you can turn. Turn it until they go off.

Will the headlights go out if the parking brake is applied?

you need to replace the relay for the headlights located in the fuse box in the engine compartment near the battery. the headlights you see when you shut off the others are likely your day time running lights
