Are Auto-Dimming Mirrors Worth It? (Explained 2023)

Auto-dimming mirrors, also known as electrochromic mirrors, have become increasingly popular in recent years. They use sensors and electronics to automatically adjust the amount of light reflected by the mirror in response to the amount of light detected by the sensor. 

This means that the mirror can reduce glare from headlights or other bright lights behind the vehicle, making it easier for the driver to see what’s behind them.

But are auto-dimming mirrors worth the extra cost? It’s a question that many car buyers ask themselves when they’re considering a new vehicle. While they may seem like a luxury feature, auto-dimming mirrors can actually provide some important safety benefits. 

By reducing glare, they can help to prevent accidents caused by temporarily blinding the driver. Additionally, they can make driving at night or in low-light conditions more comfortable and less fatiguing, which can help to improve driver alertness and reaction times.

In this article, we’ll take a closer look at the pros and cons of auto-dimming mirrors and help you decide whether they’re worth it for your driving needs.

Why Are Buyers Reluctant Towards Auto-Dimming Mirrors?

One of the most common reasons is the additional cost. Auto-dimming mirrors are often offered as part of a package or as an optional extra, which can add to the overall cost of the vehicle. Some buyers may feel that the added expense is not worth it, especially if they are on a tight budget.

Another factor that may make buyers hesitant is the perceived complexity of the technology. Some people may worry that the sensors and electronics that make the mirror work could be prone to failure, leading to additional repair costs down the road. They may prefer to stick with a traditional mirror that they perceive as more reliable.

Lastly, some drivers may find the auto-dimming feature to be a distraction, especially if they are not used to it. The sudden change in brightness can take some getting used to and may be seen as an unnecessary hassle.

Overall, while auto-dimming mirrors have many benefits, buyers may be hesitant to opt for them due to cost, concerns about reliability, and personal preferences.

How Do Auto-Dimming Mirrors Work?

Auto-dimming mirrors use a combination of sensors and electronics to automatically adjust the amount of light reflected by the mirror in response to the amount of light detected by the sensor. The basic process involves a chemical reaction that takes place within the mirror itself.

Inside the mirror, there are two layers of glass with a thin layer of electrochromic gel sandwiched between them. When an electrical current is applied to the gel, it darkens, reducing the amount of light reflected by the mirror. This is achieved through the transfer of ions between the two layers of glass, which changes the opacity of the gel.

To detect the amount of light behind the vehicle, the mirror uses a sensor located either on the mirror itself or elsewhere on the car. This sensor measures the level of ambient light and sends a signal to the mirror’s control module. The control module then adjusts the voltage supplied to the mirror, causing it to darken or lighten as needed.

Auto-dimming mirrors are designed to operate quickly and smoothly, so the driver is not distracted by sudden changes in brightness. The entire process is automated, meaning the driver does not need to manually adjust the mirror to reduce glare.

Reasons Why Auto-Dimming Mirrors Are Worth It

Auto-dimming mirrors may come with an additional cost, but they are definitely worth it for several reasons. Here are some reasons why you should consider getting an auto-dimming mirror:

• Reduced glare: Auto-dimming mirrors reduce glare from headlights and other bright lights behind your vehicle, which can be distracting and dangerous. With an auto-dimming mirror, you can maintain better visibility and focus on the road.

• Improved safety: By reducing glare, auto-dimming mirrors help prevent accidents caused by temporary blindness. This is especially useful when driving at night or in low-light conditions.

• Convenience: Auto-dimming mirrors are convenient to use because they are automated. You don’t have to manually adjust the mirror when driving at night or in low-light conditions.

• Comfort: Auto-dimming mirrors can make driving at night or in low-light conditions more comfortable and less fatiguing. This can help improve driver alertness and reaction times.

• Resale value: Vehicles with auto-dimming mirrors generally have higher resale value, which can be a bonus if you plan to sell your vehicle in the future.

Should I Get Auto-Dimming Mirrors As An Option Or Source It As An Aftermarket Part?

If you are considering getting auto-dimming mirrors, you have two options: to get them as an option when buying a new vehicle or source them as an aftermarket part.

If you are purchasing a new vehicle, it is generally recommended to opt for the auto-dimming mirrors as an option, rather than sourcing them as an aftermarket part. This is because auto-dimming mirrors are often designed to be integrated into the vehicle’s electrical system and may require specialized installation. Getting them as an option will ensure that they are properly integrated into the vehicle and functioning as intended.

On the other hand, if you already own a vehicle and want to add auto-dimming mirrors, you can consider sourcing them as an aftermarket part. However, it is important to ensure that the mirrors are compatible with your vehicle’s make and model, and that the installation is done properly. Improper installation could damage your vehicle’s electrical system or compromise the effectiveness of the mirrors.
