How to Choose the Right LED Fog Lights for Improved Visibility in a Subaru Forester?

March 10, 2024

As a Subaru Forester owner, you appreciate the vehicle’s overall performance and reliability on various terrains. However, when it comes to lighting, the factory-installed fog lamps may not always provide the best visibility, particularly during harsh weather conditions. But, worry not. Today we will guide you in choosing the right LED fog lights for your Subaru Forester, ensuring improved visibility and safety on the road.

Understanding the Basics of LED Fog Lights

Before we delve into the specifics of choosing the right LED fog lights for your Subaru Forester, it is essential to comprehend the basic dynamics of this type of light. LED stands for Light Emitting Diodes, a technology that has transformed the lighting industry, including automotive lighting, due to its superior light output and efficiency.

LED fog lights emit a wide and flat beam pattern that significantly improves visibility in foggy, rainy, or snowy conditions. They have a longer lifespan compared to conventional bulbs, making them cost-effective in the long run. Furthermore, LED lights are characterized by their bright white or yellow light, which is more visible in fog compared to the traditional halogen lights.

Evaluating the Performance and Output of LED Fog Lights

When you are in the market for new fog lights, the performance and output of the lights are crucial factors to consider. A high performing LED fog light will have a strong and intense beam that effectively penetrates through the fog, improving visibility.

Examine the lumen output of the LED fog lights. Simply put, lumens are the measure of the total quantity of visible light that a source emits. The higher the lumen rating, the brighter the light will be. For fog lights, you want something substantial but not overly bright that it blinds other drivers.

Another aspect to consider is the color temperature of the light, measured in Kelvins (K). For fog lights, you are better off with yellow light (around 3000K) since it is less reflective than white light, thus reducing glare in dense foggy conditions.

Choosing the Right LED Bulbs for Your Subaru Forester

Choosing the correct LED bulb for your Subaru Forester is essential for optimal operation. The bulb needs to be compatible with your vehicle’s model and year. For instance, the Subaru Forester series from 2014-2018 uses an H11 bulb type for the fog lights, while the 2019-2020 series uses an H16 type.

Ensure to verify the bulb size from your vehicle manual or consult with a professional before purchasing the replacement bulbs. Additionally, when selecting the LED bulb, look for features such as waterproofing and shock resistance, which add to the durability of the bulb.

Installation and Compatibility With Your Vehicle

While some of you might fancy a DIY project, installing LED fog lights is a task that requires some technical proficiency. Therefore, if you are not confident about the installation process, it is better to seek professional help.

Before you purchase the new LED fog lights, ensure they are compatible with your Subaru Forester in terms of the plug-and-play system. This system makes the installation process straightforward since the new fog light is designed to fit into the factory housing without the need for any modifications.

Consider the Brand and Price

When it comes to automotive accessories, the brand matters. Opt for reputable brands that are known for quality and durability. Brands like Diode Dynamics, Philips, and Sylvania have a track record of manufacturing reliable and high-performance LED fog lights.

While high-quality LED fog lights may come at a higher initial cost, they offer better performance and longevity, which provides value for your money. Be wary of extremely cheap options; they may not deliver the desired output, and they may not last, forcing you to replace them frequently.

Choosing the right LED fog lights for your Subaru Forester need not be a daunting task. By understanding the basics of LED lights, considering the performance and output, choosing the right bulbs, considering the vehicle compatibility and installation, and opting for a reputable brand within your budget, you can significantly enhance your vehicle’s visibility during foggy conditions. Stay safe on the roads!

Adherence to Laws and Regulations

Choosing the right LED fog lights for your Subaru Forester is important not just for visibility, but also for legal reasons. Various jurisdictions have laws and regulations in place regarding the use of fog lights. These rules govern aspects such as when you can use fog lights, the color of the light, and its intensity.

Diode Dynamics, for instance, manufactures the SS3 LED Fog Light Kit. This kit comes with the Elite Series Fog Lamp, which meets all relevant SAE and DOT regulations. This assures you that in addition to improving visibility, you are also operating within the confines of the law.

It is also worth noting that depending on where you live, the color temperature of fog lights may be regulated. As previously mentioned, a color temperature of around 3000K, which emits a yellow light, is often recommended for fog lights. However, some jurisdictions may allow white light, usually with a color temperature of around 6000K, known as cool white. Always ensure to check your local laws and regulations regarding the use of fog lights to avoid running afoul of the law.

The Effect of LED Fog Lights on Other Road Users

While the primary purpose of installing LED fog lights is to improve your visibility, it is equally important to consider the impact of the lights on other road users. By their nature, fog lights are designed to be intense, with a wide and flat beam pattern, to penetrate fog and enhance visibility. However, if not properly aligned, these lights can cause a blinding glare, which can be hazardous to other motorists.

When choosing LED fog lights, take into consideration the light pattern. Look for fog lights that provide a controlled beam pattern, such as the Diode Dynamics SS3 LED Fog Light Kit, which is designed to minimize glare to other road users.

In addition, consider the beam angle. Fog lights should be installed with a downward angle to illuminate the road and not the eyes of oncoming drivers.


Choosing the right LED fog lights for your Subaru Forester doesn’t have to be overwhelming. By understanding the basics of LED lighting, considering factors such as performance, output, and bulb type, and factoring in vehicle compatibility, installation, brand, and price, you can make an informed decision.

It’s also important to abide by your local laws and regulations on fog lights and consider the impact of your lights on other road users. Brands like Diode Dynamics, Philips, and Sylvania offer quality LED fog lights that can significantly improve visibility in your Subaru Forester, enhancing your safety on the road as you navigate through foggy conditions.

Remember, while cost is a factor to consider, the ultimate goal is to achieve improved visibility, which contributes to overall safety on the road. Therefore, be cautious of extremely cheap options that might not meet the desired light output and longevity. Stay safe, and enjoy your ride in any weather condition with your Subaru Forester fitted with the right LED fog lights.
