tail light

Replacing a tail light assembly is a common repair for many vehicle owners. Whether it’s due to damage, wear, and tear, or a faulty component, understanding the cost involved can help you plan your budget accordingly. In this article, we’ll explore the factors that influence the cost of replacing a tail light assembly and provide an estimate to help you make an informed decision.


Your vehicle’s tail light assembly is crucial to ensuring your safety on the road. It includes the tail light, brake light, turn signal, and reverse light, all contained within a single housing. Unfortunately, these assemblies can become damaged or stop functioning correctly over time, requiring a replacement.

Understanding the tail light assembly

Before diving into the cost aspect, it’s essential to understand what a tail light assembly comprises. As mentioned, it consists of multiple lights, each serving a specific purpose. The tail light provides visibility to your vehicle’s rear, especially during low-light conditions. The brake light activates when you press the pedal, alerting drivers behind you. The turn signal indicates your intention to change lanes or make a turn. At the same time, the reverse light illuminates when you shift into reverse gear, assisting you during parking and reversing maneuvers.

Reasons for replacing a tail light assembly

You may need to replace your tail light assembly for various reasons. The most common include accidents or collisions, cracked or broken lenses, water damage, electrical faults, or general wear and tear over time. It’s crucial to address any issues promptly to maintain proper visibility and comply with road safety regulations.

Types of tail light assemblies

When considering a replacement, you’ll come across two main types of tail light assemblies: OEM (Original Equipment Manufacturer) and aftermarket.

OEM (Original Equipment Manufacturer)

OEM tail light assemblies are manufactured by the same company that produced the original parts for your vehicle. These assemblies are designed to fit perfectly and provide a similar level of quality and functionality as the original one. However, OEM parts tend to be more expensive compared to aftermarket alternatives.


Third-party companies manufacture aftermarket tail light assemblies. They often offer a more comprehensive range of options, including different styles, colors, and features. While they may be more affordable, ensuring they meet safety standards and are compatible with your vehicle is essential.

Factors affecting the cost of replacement

The cost of replacing a tail light assembly can vary significantly based on several factors. Understanding these factors can help you estimate the potential expense more accurately.

The vehicle makes and models

The make and model of your vehicle play a significant role in determining the replacement cost. For example, luxury or high-end vehicles tend to have more complex and expensive tail light assemblies than economy vehicles.

Type of tail light assembly

As discussed earlier, OEM tail light assemblies are generally pricier than aftermarket options due to their quality and compatibility. However, if you opt for aftermarket assemblies, factors such as style, design, and additional features can influence the replacement price.

Labor costs

Labor costs for replacing a tail light assembly can vary depending on where you get the work done. For example, dealerships and authorized service centers often charge higher labor rates than independent mechanics or DIY replacements. Therefore, it’s essential to consider this factor when estimating the overall cost.

Average cost range for tail light assembly replacement

Now that we have discussed the factors influencing the cost let’s explore the average cost range you can expect for replacing a tail light assembly.

Low-end estimates

You may find tail light assemblies priced around $50 to $100 on the lower end of the spectrum. These are typically aftermarket options for economy vehicles and may require additional installation costs.

High-end estimates

For higher-end vehicles or OEM parts, the cost of a tail light assembly can go up significantly. You may find prices ranging from $200 to $500 or even more. It’s important to note that these estimates are general guidelines, and the actual cost may vary based on the factors mentioned earlier.

Additional costs to consider

In addition to the tail light assembly itself, there are a few other costs you should keep in mind when budgeting for a replacement.

Bulb replacement

When replacing the tail light assembly, it’s a good idea to replace the bulbs if they are worn out or nearing the end of their lifespan. Bulbs are relatively inexpensive, typically ranging from $5 to $20.

Wiring harness replacement

In some cases, the wiring harness connecting the tail light assembly to the vehicle’s electrical system may also need to be replaced. Again, it can add cost, usually $50 to $100.

Professional installation

If you’re uncomfortable performing the replacement yourself, you may have a professional mechanic handle the installation. However, this will incur additional labor costs, typically ranging from $50 to $150, depending on the job’s complexity.

DIY vs. professional replacement

Whether to replace the tail light assembly yourself or hire a professional depends on your skills, experience, and comfort level with automotive repairs. If you have the necessary tools and knowledge, opting for a DIY replacement can save you money on labor costs. However, if you need more clarification or need to familiarize yourself with the process, seeking professional assistance is recommended to ensure a proper installation.

Tips to reduce the cost of tail light assembly replacement

If you’re looking to minimize the cost of replacing a tail light assembly, consider the following tips:

  1. Compare prices: Shop around and compare prices from different suppliers to find the best deal on the tail light assembly.
  2. Consider aftermarket options: Depending on your budget and preferences, aftermarket tail light assemblies can offer a more affordable alternative without compromising quality.
  3. DIY installation: If you have the necessary skills and tools, replacing the tail light assembly yourself can save you money on labor costs.
  4. Seek multiple quotes: If you decide to hire a professional, obtain quotes from different mechanics or service centers to ensure you get a fair installation price.


Replacing a tail light assembly ensures your vehicle remains safe and roadworthy. The replacement cost can vary based on factors such as the vehicle make and model, type of assembly, and labor costs. By considering these factors, exploring different options, and making informed decisions, you can budget for the replacement effectively while ensuring the best value for your money.
