What are car tail lights? Their types & how they work

Car Taillights (the lights of the back of the car) create a form of communication with other vehicles on the road and serve to prevent collision accidents resulting from impaired visibility. However, their aesthetic role cannot be denied either; brands compete to innovate taillight designs inspired by natural objects and fierce animals.

Taillights can enhance or diminish the driving experience for both the driver and the surrounding vehicles. Driving behind a car with broken or malfunctioning lights is one of the worst and most dangerous experiences on the road. In this article, we will provide an overview of different types of taillights, how they work, and the safety standards associated with them.

Types of Tail Lights

With numerous options for car taillights, there are three basic types:

  1. LED Lights: LED lights have dominated the realm of rear lights in cars despite being relatively recent. Their production and integration into the external structure of cars began around 2000. LED lights are known for energy efficiency, providing very bright and effective lighting.
  2. Xenon Lights: Xenon lights consist of a compressed glass capsule containing xenon gas mixed with other flammable gases. The gas mixture inside the xenon light requires a special electrical system, providing up to 25 kilovolts to operate the light. Xenon lights are characterized by radiant illumination, three times that of halogen lights, with a 40% energy-saving and longer service life.
  3. Halogen Lights: Halogen lights are the foundation of modern car taillights. They can outperform others in terms of availability and ease of replacement when faults occur. Halogen lights produce warm light with a lower brightness level than other types.

How Taillights Work:

Operating taillights is usually straightforward as they are typically wired to a switch responsible for operating the front lights. Therefore, once you turn on the front lights, the rear lights will illuminate accordingly.
In the case of automatic taillights, this type is directly connected to the car’s battery. Consequently, starting the car will automatically activate the taillights.

Tips for Replacing Taillights:

Anyone can replace malfunctioning taillights or switch from one type to another. However, the following guidelines may facilitate the process, saving time and effort:

  1. Gently remove the glass or plastic cover surrounding the lights to avoid scratching or breaking it.
  2. If there is difficulty removing the cover, gently pull it slightly outward and then reach in to replace the bulb.
  3. Some car bulbs need only a quarter-turn to come out.
  4. Pay attention to the fact that the issue sometimes comes from the bulb holder, not the light itself.
  5. If there are external scratches on the light cover, solve it with transparent glue and then polish the surface.

Safety with Car Taillights:

As mentioned above, taillights play a crucial role in safe driving. They are located at the rear edge of the car, helping to avoid collisions and accidents. They enable the driver in the car behind you to notice your car, along with facilitating visibility in different weather conditions, especially in adverse weather such as rain or sandstorms. Taillights signal to rear cars to stop or slow down when changing lanes, contributing to overall road safety.
