If you want to know more about car lights, you are in the right place as we will show you the different types and the role they play in the car.
Car Light Types, Names with pictures
In the car lighting system, the headlights are the most famous and equally important to the motorist. They come as a pair, located in the car’s frontal area, though in other vehicle models, they may be four and serve cosmetic purposes or brand signature. The headlights play a vital role in illumination, especially in dark conditions, allowing the driver to see the road ahead.

There are two types of car headlights; low beam and high beam lights. The low beam lights give sufficient lateral and forward lighting. On the other hand, high beam lights provide centered light distribution with no control of glare and are ideal for roads with no visible traffic.
As their name hints, tail lights are at the back of the car and produce a red light. They work in tandem with the headlight, such that when the headlight is on, they are also on. Their primary purpose is to let motorists know that there is a car ahead of them and how far it is.
Fog lights help the driver see in foggy conditions. You find this type of light below the headlights, and it emits a wide beam of light, with a sharp cutoff preventing the light from refracting off the fog and glaring back to the driver. They usually come into play when the headlights are not so effective, especially when there is too much fog.
Daytime Running Lamp
The daytime running lights are present in both the front and the rear of the vehicle, and they automatically turn on when the car is on a drive or when the handbrake is down. Their main purpose is to help other road users notice the vehicle, though they may be distractive. Some car models have the option of turning them off.
The signal lights are critical in driving and can go by turn signals or blinkers. You will find them at both the front and the rear of the car by the side of the headlights and tail lights. You activate these lights to signal other drivers that you are taking a turn, indicating the direction you are taking. They play a significant role in communicating with other drivers when on the road.
On the car’s rear, to the side of the taillights, are the brake lights. As their name hints, they turn on when you turn on the brake, and they signal other drivers that you are slowing down. While they are not prone to misuse, you should maintain them properly to prevent the occasional burnout.
The hazard lights are flashing lights in the front and the rear of the car, which you have to manually turn on in case of distress. You press the hazard button on the dashboard to alert other motorists that your car is not in the best driving shape, such as if you have alternator problems.
Parking lights are also on the front and back of the car. On the front, they have either a white or amber appearance, while on the back, they are red. They should be visible for 500 feet, and you use them when parking. In most states, it is illegal to drive with the parking lights on.
Interior lights are the ones found inside the car and help brighten the inside. You should not use them for long, especially when driving, as they can affect your judgment.
Other Types of Lights
The lights come from bulbs, and there are different types of car light bulbs, the common ones being LED, halogen, and xenon lights. Let us have a look at these types.
LED lights are standard in modern vehicles or those with aftermarket tuning. The LED lights’ primary purpose is cosmetic, primarily on the headlight area, where they give the car’s front part a sharper look. They are energy efficient in addition to being less prone to heating up. This makes them long-lasting and easy to maintain.
Some care will feature this type of car light on the body or even wheels to make the car stand out.
Halogen lights are the standard lights in most vehicles and use a combination of gases such as nitrogen and argon inside a tube with a tungsten filament, which heats up to produce light. They are cheap and easy to care for, though they have the issue of overheating.
The xenon lights also go by high-intensity discharge (HID) lamps. They work in an almost similar manner to halogen lights by heating gases and metals to produce lights. The main difference is that they use rare metals to light up.
They produce much light compared to halogen lights of the same wattage. They are not common due to the high cost of the rare metals and their uncontrolled glare.
