  • Rear Fog Lamps: These are more useful than front fog lamps. They are a bright red light (similar to a brake light) that is lit in poor visibility to make the vehicle more specific for low traffic.

#15 Fender


The fender is the curved part of the car’s body that sits on top of the wheels and holds them in place. It is not only a safety component but also enhances the overall look of your vehicle. Its primary function is to shield and protect the passenger compartments by preventing sand, mud, rocks, liquids, and other roads spray from being thrown into the air by the rotating tire.

#16 Fender Liner

In every type of vehicle, each wheel has a separate fender liner. The function of fender liners is to prevent dirt, mud, water, environmental toxins, and other impurities from seeping into the engine bay causing serious damage.

In addition, it also helps to protect the wires and other components inside the wheel well from corrosion. Driving a vehicle without a fender liner is not recommended as it acts as both a buffer and a barrier between your car’s engine, hood, radiator, headlights, and windshield.

#17 Roof

Car Roof

A roof is the top part of a vehicle that sits above the passenger compartment, protecting the vehicle occupants from sunlight, wind, rain, and other external elements.

The car ceilings are typically coated with headliners that provide insulation against heat and noise, and also hide wires and hardware for electrical components, antennas, and other accessories.

#18 Sunroof

Car Sunroof

The sunroof gives passengers a clear view of the sky, keeps the car ventilated, and lets the sunlight in, creating a feeling of open space. This is a type of panel on the roof of a car that either slides or can be pulled out to allow light in.

These are quite expensive as you will have to pay extra for all the mechanisms that operate the sunroof. They are also high maintenance because the rubber, glass, motor, and all other components require frequent maintenance.

#19 Mirrors

There are mainly two types of mirrors used in vehicles that are side-view mirrors and rear-view mirrors.

1. Side-View Mirror

Side-View Mirror

These are also known as wing mirrors. These mirrors are located on the exterior of the vehicles to help the driver see areas behind and side of the vehicle or outside the driver’s peripheral vision.

Also, it will alert the driver about possible accidents that happen from behind. The advantage of side mirrors being convex is that you get a wider view of each side of the car which helps reduce blind spots.

2. Rear-View Mirror

Read-View Mirror

They serve multiple purposes that help to keep you safe as a driver. It gives you an alert driving experience by allowing you to see behind your vehicle without turning your head. In addition, they are especially important when a vehicle is moving in reverse gear.

#21 Window Glass

Window Glass

The basic reason for the use of window glass in cars is visibility. Whether at the front, side, or rear of the car, the visibility managed by the glass is extremely useful.

The glass allows passengers to see where they are going and allows natural sunlight or artificial street lighting to enter the vehicle. There are usually two types of window glass used, single-layer toughened glass or laminated safety glass.

#22 Quarter Window

Quarter Window

It is a type of side window that is located before the front door glass or after the rear door glass. In some models, the fixed quarter window may be placed in the corner or “C-pillar” of the vehicle.

They provide a quick peek of the road around the vehicle so that the driver can turn, speed up, park, or change lanes safely. These windows are often found on older vehicles. These are small triangular in shape at the front and separate from the main window.

#23 Door Handle

Door Handle

Door handles help the driver or passengers to get in or out of the car. Door handles are the most important component as they contain door locks. Usually, we use the door handle to unlock the car from outside or inside. There are different types of door handles available according to the car model.

#24 Trunk or Decklids

The trunk lid (also known as dickey) of a car is the main storage or luggage compartment which is often located at the rear of the vehicle such as sedan, coupe, or convertible.

The trunk of a car is more than just storage and must be used for the actual purpose of carrying goods. It is an important storage space, so it is necessary to clean it regularly. Also, keep in mind that if you are loading more luggage then the engine will consume more fuel.

#25 Mud Flaps

Mud Flaps

Whether you have a car, an SUV, or a truck, getting mud flaps for your vehicle is necessary. This is useful when your tires are constantly exposed to mud, dirt, rocks, salt, water, and other elements on the road.

As the name suggests, mud flaps are meant to catch dirt and stones and ensure that it doesn’t fly straight into your vehicle from back and front. A car without mud flaps will require more regular maintenance.

#26 Wheels


The most basic and important parts of a car body that have always been in use are the wheels. These are circular forms that generate rotary motion and are responsible for moving the car from one point to another.

The tire is the rubber part that wraps around the wheel and grips the road surface. Although the wheels can spin without tires, the car does not go very far. Without them, the wheels of the car would slip on the road faster without moving forward. Nowadays, there are different types of tires easily available in the market.

#27 Hubcap


It is a decorative disc on an automobile wheel that covers the central part of the wheel. The function of the hubcap is to cover wheel hub and wheel fasteners to reduce the dirt and moisture collection. It also enhances the overall structure of the wheel.

When you drive without a hub cap, all kinds of dirt and debris get trapped in the tires, which can lead to tire wear and tear. By having a hubcap, foreign particles do not damage your wheels and provide longer life.

#28 Dashboard


The dashboard is the controlling panel of any kind of vehicle. This is also known as dash or instrument panel. It lies within the central console of a vehicle and is usually located directly ahead of the drive.

The dashboard shows the driver tools and controls for operating the vehicle. It has simple controls (eg, steering wheel) and an array of instrumentation to show speed, fuel level, and oil pressure. Modern types usually feature information, climate control, and entertainment systems.

#29 Number Plate

Number Plate

Due to the Motor Vehicle Act of the government, it is necessary to have a number plate on every vehicle. The number plate reflects the very specific details of the vehicle and consists of four important elements.

It also gives a unique identity to the vehicle. Nowadays, all vehicles on the road are preferred to display registration on both the front and rear sides of the vehicle.

#30 Tail Lights

 Tail Lights

The taillights consider the safety aspect of the vehicle. These lights allow your vehicle to be seen during low visibility conditions and alert other drivers that you are slowing down. On most vehicles, the tail light is red and the brake light is more bright red.

The taillights stay ON when you turn ON your headlights or when your parking brake is ON. While the brake light will light up immediately when you apply pressure to the brakes. So the brake light and tail lights are not the same.

Wrapping It Up

In conclusion, the car is beneficial for its convenience. The above-mentioned car body parts are very essential for every vehicle. Without these parts, the vehicle may not perform well on the road and that can lead to heavy breakdowns or accidents.
