Short answer, "Yes, you can use them until the battery dies."
Will you be driving the car? The engine will die too (probably with no warning) when the battery voltage drops too low to power the computer and/or ignition system. (Don't ask me how I know.) If the lights are on, that's going to happen sooner rather than later.
Also, you aren't doing your battery any favors. Most car batteries are so-called engine starting batteries. They are designed to be able to deliver relatively high cranking current for their size, but the tradeoff is that they are not designed to be deeply discharged. Every time you let an engine-starting battery go dead, you may be taking another few weeks-to-months off its life expectency.
Almost all cars use a bulb with two element in it. One for the tail light and one for the brake. It's rare for them to both burn out at the same time.
because working principle of both the things are same.The motor converts electrical energy in to mechanical via magnetic induction and generator do the exact opposite of this.And yes,you should use 'electricity generator' not only 'generator'.
Auto batteries are made to use in cars. They are what operates your car. If you did not have a battery you would not be able to run the engine in the car. You also would not be able to turn on the lights. The "Primary" use of an auto battery is to start the vehicle and then store the electricity for re-use. Then the generator/alternator can keep up with the lights, etc. If the generator/alternator dies then the auto can usually run for a short time on the battery reserve.
Some cars have LED lights, but most use a special light bulb that can be purchased at your next service.
Generator and the batteries it charges.

use lights on cars
So other cars can see them in the dark. Neon colours are bright and fluorescent.
There are numerous types of lights that can be used. Flashlights and the light sticks that can be cracked to release light can be used. Also solar powered lights, push button stick on lights, and lights that can be run off a generator are options.
Depends on what type of generator you are talking about. A Generator in an older car uses energy from the engine to produce electricity. New cars use alternators. A generator for a house can use Natural Gas, Propane, Diesel, Gasoline, or just about any combustible fluid. There are also wind and hydro electric powered generators.
Generators can be used to power many electrical appliances in a house during a power outage. Depending on what size you have, a generator can power a refrigerator, oven, lights, even an air conditioner.
Be brave and buy a new one. Or use a membership generator!
