with the information you've given, it sounds like a weak battery.
check the starter, or maybe check the battery may be enough voltage for lights, but not to crank the engine over.
if you leave any lights on in the car you may cause you a flat battery. if you leave any lights on in the car you may cause you a flat battery.
Weak battery? Loose or corroded battery cables? Starter solenoid?
Well not the starter. The starter is used to start spinning the engine and draws its power from the battery. The alternator uses the engines belt to recharge the battery and to power the cars electronics as well as lights. When you shut the engine off, the power then draws from the battery.
Seized engine? Weak battery? Corroded or loose battery cables? Bad starter or starter solenoid? Bad neutral or clutch safety switch? Bad ignition switch?
Some times the battery will have enough power to turn lights on but not enough to turn the engine over. Try to jump start it or replace battery with one you know is charged. By the way-nice car.
Yes, the clicking is the starter, but there's probably nothing wrong with it. Your battery doesn't have enough juice to turn the starter motor (draws lots of current), but still has enough to turn on the lights and accessories. Try jump starting it or trickle charge the battery.

When your lights are on and your engine is not running you are taking the power for your car lights directly from your battery. If you leave them on long enough, you will run down your battery and your car will not start. Then you will need a jump.
The battery has insufficient power to crank the engine but enough power to power the lights. The starter motor needs considerably more power than the headlight bulbs.
The battery power is not reaching the starter. You have other problems...
