Testing a battery's performance and reserve (or amp-hour) capacity is not just a matter of seeing whether it will hold a charge (or checking the electric eye found on some batteries to see if it is green), so testing is best done by an auto technician at a repair shop. A professional can also determine if any problems you are having may be caused by something else, like your battery terminals or alternator. If a bad battery is the culprit, your mechanic will help you choose and install an appropriate replacement.
Light bulb: this invention is of course, revolutionary in all. The bulb replaced the gas-oil lamps which drivers hanged in the side of the car. Needless to say that it gave the driver the possibility of night driving thus more autonomy and safety on the road. The first bulbs that were used had a short life-span, but gradually built up to today ones that are enduring, long lasting and give us a comfortable night drive.
