With technology in cars advancing all the time there are more and more electrical systems being used by all car manufacturers to keep up to date with their competition. There are electronics in cars today that are as advanced as home entertainment centres with DVD players, cd players with high tech sound systems etc. However, although these systems may be useful in providing entertainment facilities and systems such as electric windows and cruise control making the car easier for the driver to manage, it also means there is more that can go wrong. With some problems you won't be able to fix them unless you are a professional in the trade but there are some electrical problems that you can solve your self, below are some instructions to help you fix some of the more simple problems.

With a simple problem such as a burnt out bulb on your head lights or tail lights there is also the hidden danger that many people don't seem to think about. How many people do you see driving the streets with one of their headlights out totally un-aware of the danger and not realising how simple it is to actually change it themselves? There are many of us who think it will be ok to leave until the car gets serviced, but these days if you are pulled over for having one of your car lights out it is a lot more expensive than buying a new bulb previously. Here are the simple instructions to follow while changing the light bulb in your headlights:

• You need to make sure you have the correct bulb to replace it (most cars use the same kind of bulb, however, there is one called a sealed beam headlight that comes with it own instructions) and the correct screw driver to remove the front of the headlight.
• Once the cover is removed turn the bulb retainer counter clockwise until it is removed.
• Then when taking the bulb out of the retainer note the direction and poison of the bulb as there will only be a certain way the bulb will fit in.
• Then, being careful not to touch the glass with your fingers as this can cause a hot spot from the oils on your fingers and in turn cause the bulb to fail quicker maybe even explode, place the new bulb into the same position as the old in the retainer.
• After the bulb is placed in the retainer put the bulb and retainer back into place in the connector.
• After you have finished this process all that's left to do is replace the cover of the headlight with the screwdriver ensuring it is tightly fitted.

With your tail lights you follow a similar process except firstly you will need to see how you access the light itself it will either be from the trunk where there is a back panel for you to remove, or it will be the same as the head light and you simply screw off the front of the light. Then you just follow the instructions as above making sure you have the correct bulb for your model of car, to be totally sure you can always take the old bulb into the car shop when you buy the new bulb.

With faults such as electric windows failing and other electronics on the vehicle not functioning correctly guides are available to instruct you on how to determine the problem and then how to repair it. Of course there are going to be situations where no matter what you try you will be unable to fix or even determine what the problem is, this meaning you will have to take your vehicle into a professional. When this is the case ensure the person that is carrying the work out for you is in deed a qualified car electrician as they have to have another qualification as well as just a mechanic one before they can carry out the work on your vehicle.
