Your battery is probably almost dead either due to an old battery not retaining a charge or your alternator is dead. both are easy to replace assuming you have basic mechanics skills. Test by using a volt meter to see if you are getting at least 12 volts coming off of the alternator. Touch the end of the bolt that is attached to the wire and then touch something grounded. If the volt meter reads at least 12 volts, then you need to replace the battery. Even if it is the alternator, in my experience, once your alternator goes, the battery is close to follow. They just don't like to be drained to nothing repeatedly. The alternator should cost you around $200. Be sure to save the old one and return it to the auto parts place for a core refund, probably about $50.

What is the problem when head lights are on and the tail lights dont work but the brake lights work?

If the headlights are on and brake lights work but not the tail lights, it is possible there is a short in the electrical wires. Another cause for this could be that the tail light bulbs are burned out. Most vehicles have more than one bulb inside the tail lights to control different lights at the same time.
