Your alternator may not be putting out enough Amps to charge your battery and run your headlights as well.
You can test this by measuring the voltage from the battery with a multimeter. With the car running the volts should be around 14 or more on a 12 volt battery. Try it with the lights on too.

If lights do not come on, the battery is dead (try jump-starting) or there is a bad connection (loose cable), or a short in the electrical system. If headlights come on, but dashboard lights do not light up - check the ignition (cylinder / switch)
