I want to know if there is a way to power multiple (very small) L.E.D lights with only a few AA batteries. And i need a way to do it using ONLY household items. it's for a project and i cant go out and buy anything except for the bulbs and batteries. 
i know it's weird. but can i use the cable for a pair of headphones to connect them or something???? help please
and also, what about a small 12v bulb for a car taillight
and what exactly do i have to do to make it work?????
You will need 8 AA batteries. You will hook them all in series (make 4 groups of two, and connect the ends together using aluminum foil. Wrap the whole thing together with rubber bands to hold the connections tight, and wrap it up with duct tape).
Now you have a 12 Volt supply that will power the taillight bulb directly. For wire, you can again use foil, or the wire that is normally used to hang pictures. Connect one end of the bulb to the + and the other to the - of the battery pack, and there you go.
For the LEDs, it is a bit tougher. Your 12V power supply will still do a great job. You can hook 4 LEDs in series (twist the leads together, but remember to keep the polarities correct, + to - for each connection). Now you need a resistor to limit the current. I suggest that you use a night light bulb (one of those with a small screw base) to put in series with the LEDs. This will limit the current to something safe.
The big light bulb suggested by one of the other respondents is a bad idea, because the cold resistance of an incandescent bulb is about 1/15th of the hot resistance, so his calculation is way off.
