Importance of Car Lights
Car lights play various roles in a car. There are different types of car lights, each serving a different purpose in your car. Apart from visibility, they are also essential indicators and help with the safety of other motorists on the road.
Different Car Lights & Their Functions
Car lights are divided into internal and external sections based on their functions and uses. This section will explore the different car lights and their functions.
Internal Car Lights
Interior automotive lighting is a broader term divided into three categories: displays and indicators, illumination, and accent lighting.
- Displays and Indicators: The display and indicator lights are used to obtain information, such as the standard dashboard instrumentation information or any more complex information from a navigation system.
- Illumination: The interior illumination system enables drivers or passengers to see something else in the car, for instance, dome lights, mirror lights, etc.
- Accent Lighting: The accent lighting provides styling and aesthetic cue, creating a desired ambiance in the car or locating various controls, such as the power window controls and radio knobs, in a darkened cabin.
Let’s explore different internal lights.
The instrument panel is a section of the vehicle’s dashboard sitting behind the steering wheel. It consists of multiple gauges and lights, updating the drivers on the vehicle’s status. For example, the check engine light may illuminate the instrument panel when there is a problem with the engine. Moreover, the instrument panel gets illuminated in most cars in the dark.
The trunk light is a small bulb on top of the car’s trunk. Its main function is to light up the trunk whenever the lid opens. Since the trunk light is used less often, it can last many years. Replacing it will cost you somewhere between $20 to $100.
Car Door Illuminations/Puddle Light
Puddle lights, also known as car door lights, are the car lamps below the mirror. These lights illuminate the car ground near the door every time you open the door. Puddle lights prevent people from stepping into puddles or anything murky while sitting in the car.
Overhead Lighting/Dome lights/ Courtesy Lights
The lights are present to illuminate your vehicle’s cabin in the dark. They are located on the overhead console, and each light has a button to turn them on or off. Also known as dome or courtesy lights, the overhead lights are located on the vehicle’s ceiling and turn on when people enter or exit the car. Normally, these lights will stay on until you start the vehicle so the passengers can fasten their seat belts.
Storage Box Lighting
Storage box light is present in the storage compartment of most vehicles. It will light the compartment in the dark to make it easy for you to search for the contents of the storage box. However, most cars today don’t have this light in the glove box, and many drivers may also light the compartment using LED lights.
External Car Lights
External car lights are all the lights outside the car and provide better visibility to drivers in the dark, rainy, or foggy seasons. It covers all the lights around the perimeter of the car. Also, the law requires exterior car lighting, and rigid regulations are present that you must fulfill for the light function to become road-legal.

High-Mount Stop Light
A high-mounted stop lamp is fitted in the central, high-mounted position of the vehicle’s rear. It is generally higher than the stop lamps on the vehicle’s side. It operates when you activate the service brake, meaning when you step on the brake pedal.
Tail Turn Signal Light
Tail lights are present at the vehicle’s rear and produce only red lights to enable other vehicles to spot you while you turn or overtake. Moreover, the drivers traveling behind you can recognize you’re there and how far ahead your vehicle is.
The brake light is the same as a tail light that will light up whenever the driver steps on the brake pedal or stops the car. While the brake lights are not prone to misuse, you must maintain them to prevent occasional burnout.
The reverse light or backlight is present at the back of the car and is used to warn other drivers about your car’s movement. Generally, reverse lights are white to differentiate them from the tail lights and will light up whenever you move your car backward.
High/low Beam Light
Headlights are the essential light of a car and illuminate the path sufficiently to ensure safe night driving and provide two high and low beams.
There are three types of headlights available in the market nowadays.
- HID Headlights: HID headlights contain HID bulbs and are brighter than standard headlights.
- LED Headlights: LED headlights are energy-efficient and produce brighter, whiter light than standard ones.
- Halogen Headlights: Halogen headlights are not as bright as LED and HID lights and consume more energy than them.
License Plate Light
License plate lights are the lights in the rear of your car that illuminate your license plate to other drivers. It enables other drivers to read your license plate number in the dark. However, only some cars have a license plate light.
Front Turn Signal Light
Signal lights play a vital role in the safety of your car. They indicate deceleration and a change in the direction of your vehicle or whenever you switch lanes. This enables drivers to switch lanes smoothly and become visible to other drivers on the road when it is dark or during poor visibility.
Front Fog Light
The front fog light is located below the headlight assembly and emits a wide beam of light with a sharp cutoff at the top to prevent it from reflecting off the fog. Such lights aid visibility whenever the weather is bad or may reduce the ability to see the road ahead.
