How do light a light bulb with a car battery?

A car battery normally supplies 12.5 volts at full charge. If the light bulb you are trying to light is a 12 volt bulb then make a connection with the +(positive) battery terminal to the small lead button at end of the bulb, and the - (negative) terminal to the metal side of the bulb. If the battery is charged, the light should work. If the bulb is a higher voltage type you must connect more batteries in series until the proper voltage is reached. WARNING...With more batteries connected in series, the voltage could become dangerous. Do not use more than two batteries in series unless you have an experienced electrician to apply safety techniques. If your battery is 12 volts, an auto lamp up to 24 volts will light up. the 24 volt bulb will be half as bright. Over the years, I have replaced dashboard lamps with 14 volt bulbs because they will last longer because they are rated for a higher voltage but fed with a lower voltage.


Is 12 volt is enough for a 100 watt light bulb?

12 volts is enough for a 12-volt 100-watt light bulb. It would not be enough for a 120-volt or 240-volt bulb.


If you have brighter bulbs will the battery last longer or will it run down quickly?

That does not depend directly on the brightness of the bulb, it depends on the current drawn by the bulb (which depends on the efficiency of the bulb). For example an incandescent bulb will draw much more current than a much brighter CFL bulb or LED bulb. Therefor switching to an brighter LED bulb can make the battery last much longer while switching to a brighter incandescent bulb will make the battery run down quicker.
