The cause of this was that the car was becoming not only a mean of transportation but a necessity in every day life. The further expansion of the car depended on it to be easy to use, that almost everyone could use it and you can learn to drive it relatively simply. One of the most important fields of car industry that did this is car electrics. Here's our top list of the most important electric inventions on the car:
In case you don't know who take your car to for auto electrical repairs, you can ask for references from fellow motorists; ideally friends and relatives who are unlikely to mislead you in this (potentially sensitive) matter. As long as they have faced such situations before, they are likely to guide you on which service providers to visit; or at least which service providers to avoid.

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.
