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.
When doing auto electrical repair, the first vehicle component your should acquire knowledge about is the car battery.

In addition the auto battery helps to operate all the electrical accessories installed on your motorcar. An auto battery should last 3-5 years in average climates. Extreme hot or cold climates however, will reduce this to only 2-3 years.
Of course, there are plenty of wiring problems an engine can experience and they can be very difficult to locate unless the mechanic is experienced. Analysing electrical problems requires using special equipment combined with mechanic expertise. Today's engines are extremely sophisticated combinations of electronics, electrical wiring, and moving parts and seem like they are half-computer and half-mechanical.
Battery: this invention has made the complete car electric system possible. From the old heavy and unreliable ones to today's modern batteries, it's something that a car can't go without. In the invention of the batteries lay the seeds of today's modern electric-cars. Spark plug: today it's an usual item in car mechanics. But think of the people that invented it!! Lighting the fuel-air mix with an electric spark, simply amassing. How great it is, proves the fact that the principle is unchanged ever since. Every invention on the car has it's purpose and, in mechanical terms,it's own beauty. Ranking of this kind doesn't neglect all of the other marvels on the car, on the contrary. The genius in these 5 inventions is that they stayed basically unchanged for all of these years giving the driver comfort, safety and reliability
