During the lifetime of most of those reading this article we’ve gone from the only sources for cars parts was what was available locally – the dealership, car parts store
One would assume that for one of the simplest of all DIY car service, and oil change, that I’ll you’d have to do is walk up to the counter at your local parts store and ask for a filter for your 2014 Ford Focus
For such small components, external lights and indicators on your vehicle play a very important role and help your car be legally compliant. It is the law that you must have working indicators and if they don't work, your car will not pass the MoT. You also need functioning brake lights.
However, not having working indicators means that when you turn you are failing to inform other road users and run the risk of causing an accident. As soon as you know an indicator is not working, you must replace it. If the indicator doesn't work and the bulb appears to be functional then it maybe a broken indicator relay.
Replacing indicator bulbs is inexpensive and finding the right bulbs, relays and casings is a straightforward process.
As for your car headlamps, these are an essential part of a functioning car and your visibility is important. Again, the bulbs are relatively cheap to buy and it's possible to buy new casings as well which helps if you are looking to change the style of your car. You also need to appreciate that carrying spare light bulbs for your car is a sensible thing to do and if you travel in some European countries you will find it's a legal requirement to do so.
For those who are looking for headlamps, you will need to find car bulbs that work for your car and have dual functions. The first is for a dipped beam so you can use the headlamps in built-up areas and the high beam which is a stronger beam of light which is used mainly for unlit roads. It is the high beam lights that you need to switch off when there's on-coming traffic including pedestrians and cyclists since these high beams may blind them and create an issue.
There are obvious issues regarding your car's safety, plus for those who are traveling in it, if your brake lights are not working. If the vehicles traveling behind you do not appreciate that you are braking for a purpose, for example, to avoid a collision with something or someone in front of you, then they risk colliding into the rear of your vehicle. Brake lights, therefore, play a crucial safety function and as soon as you are aware they do not work, they should be replaced.
You also need to ensure that you're reversing light works when you engage reverse gear and it's also important that your rear fog lamp works as well whenever necessary. Though you may not use your fog lamp on a regular basis, it still fulfills an important safety function. It also needs to be appreciated that fog lights are not just for use in foggy weather; many drivers will use them in the very heavy rain and snow to help traffic behind them know where their vehicle is. Some cars have fog lights at the front as well.
Cars also have side lights which can be used for parking on unlit roads and for when you park facing the wrong way into traffic. The side lights can be used at night in built-up areas so other traffic can see you. There's also, for modern cars, daytime running lights which are side lights that are permanently on and have been introduced to comply with European Union laws.
The replacement parts for external lights and indicators may include:
Boot or tailgate lamp cluster
Boot lock catch assembly
