Yes, if the bulb is of the right voltage, as in a torch (flashlight).
Use another vehicle to jump start it, or replace the battery, or charge the dead battery with a charger.
No
Check your charge in your battery. Just because all things turn on does not mean your battery has enough power to start the engine. Charge your battery or get a jump start.
If by "fast click" you mean a series of rapid clicks, that is an indication of either a flat (low) battery or loose battery cable(s).
dead battery or a broken wire between the battery and the starter
To jump-start a Porsche Boxster S, first ensure both vehicles are turned off. Connect the positive (red) jumper cable to the positive terminal of the dead battery and then to the positive terminal of the working battery. Next, connect the negative (black) jumper cable to the negative terminal of the working battery and attach the other end to a metal ground point on the Boxster, away from the battery. Start the working vehicle, let it run for a few minutes, then attempt to start the Boxster.
It can start with just one battery.
The problem is not the starter. The battery is either not holding or not receiving enough charge. Problem could be (1) loose alternator beltl (2) loose/corroded battery cable(s); (3) dead cell(s) in the battery; (4) bad alternator.
Sounds like the battery went dead or you have loose/dirty battery connections.
If you changed the battery on a Saturn S-Series 201 and the car will crank over, but won't start, the security system needs reset. Do this by inserting the key and turning it halfway. Leave it this way for 10 minutes before trying to start the car.
Won't start and won't turn over are 2 different things. If it will not turn over then look at the starter or ignition switch.
Weak battery and no gas can both cause a no start.Weak battery and no gas can both cause a no start.
