I think you mean, "Why do my headlights turn of while I'm driving" There might be an issue with your fuses or eletrical system.
If the car turns off while driving, it can be a sign of a bad ground. It can also mean a fuel system problem.

Typically it is because the connector inside the console that electronically switches the 4wd system on is not connected properly...This happened to me...I pulled it out and pushed it back in and the lights went off when in 2wd or Auto 4wd mode...
Simple answer is the alternator
There are several reasons why a 1995 Dodge Caravan may turn off while driving. One reason could be in the electrical system. Another reason could be in the fuel system.
Probably fuel pump failure.
The alarm should turn off once you start the car. If the alarm is going off while you are driving, pull over and remove the fuse.
When stopped or < 3 MPH push the 4WD button again and the gree light should go off and put you in 2WD.
If you are in a rough-terrain area, you can press the "lock" button and it will turn on. Once you hit 25 miles and hour, the computer will turn that off and not turn 4WD back on until it senses that it needs to (slipperiness, etc.).
No, on most cars the overdrive is always ON unless you turn it off.
