In this blog post, we will compare LED and halogen fog light bulbs, discussing their features, performance, pros, and cons, and helping you decide which is the right choice for your vehicle. We’ll also explore some of the best LED fog light bulbs, including those from Underground Lighting, and provide you with useful tips on upgrading your fog lights.
When choosing between LED and halogen fog lights, it’s important to understand the fundamental differences between these two types of bulbs. Let’s break down their key characteristics:
LED Fog Lights: LED (Light Emitting Diode) technology is a modern and energy-efficient lighting solution. LEDs are solid-state lights that emit light when an electrical current passes through them. They are highly durable and consume less power compared to traditional lighting technologies like halogen.
Halogen Fog Lights: Halogen lights are a type of incandescent bulb that uses a tungsten filament surrounded by halogen gas to produce light. They are the older, traditional fog light technology and have been used in vehicles for decades.
LED Fog Lights: LED bulbs are known for their superior brightness. They produce a more focused beam of light with higher lumen output, which helps increase visibility in foggy, rainy, or snowy conditions. LED fog lights tend to have a whiter, more intense light, making them ideal for modern vehicles.
Halogen Fog Lights: Halogen bulbs are less bright than LEDs and produce a yellowish light that is more diffused. While they still provide adequate illumination, halogen fog lights are not as effective in cutting through dense fog or other poor weather conditions.
LED Fog Lights: LED fog lights are known for their impressive lifespan. They can last up to 25,000 hours or more, making them a long-lasting solution that doesn’t need frequent replacement. This makes them a cost-effective optionin the long run.
Halogen Fog Lights: Halogen bulbs have a shorter lifespan compared to LEDs, typically around 500 to 1,000 hours. This means you’ll need to replace halogen bulbs more frequently, which can be a hassle and increase overall maintenance costs.
LED Fog Lights: LED fog lights are highly energy-efficient, using less power to generate the same or more light compared to halogen bulbs. This means your vehicle’s electrical system is not overburdened, and it can help reduce fuel consumption.
Halogen Fog Lights: Halogen bulbs consume more power and generate more heat than LED bulbs. This lower energy efficiency can put additional strain on your vehicle's electrical system.
LED Fog Lights: LED fog lights are generally more expensive upfront compared to halogen bulbs. However, the long lifespan and energy efficiency of LEDs make them a more cost-effective option in the long term.
Halogen Fog Lights: Halogen fog lights are more affordable initially but will need to be replaced more frequently, which can add up over time.

Warm Light Color: The yellowish hue of halogen fog lights can be easier on the eyes in certain driving conditions, such as when driving at night.
Widely Available: Halogen bulbs are widely available and come in various sizes and styles to fit different vehicle makes and models.
However, despite these advantages, halogen bulbs have a shorter lifespan, are less energy-efficient, and offer inferior performance in foggy or adverse weather conditions when compared to LEDs.
When deciding between LED and halogen fog lights, consider the following factors:
Driving Conditions: If you frequently drive in foggy, rainy, or snowy conditions, LED fog lights are the better choice due to their superior brightness and beam focus.
Budget: If you're on a tight budget, halogen fog lights may be a more affordable initial investment, but keep in mind that you’ll need to replace them more often.
Lifespan and Efficiency: For long-term savings and better energy efficiency, LED fog lights are the superior option. They last longer and use less power, saving you money in the long run.

In some cases, you might need yellow fog light or white fog lights in your vehicle, for example:
1. "I was driving at night and noticed that my fog lights weren't doing me any justice especially on snow / raining days."
2. "I noticed I was not getting a sufficient amount of light with the stock halogen bulbs and felt it would be nice to have the yellow bulbs to light up the road much more."
The halogen fog light bulbs are tend to be K which enclose to sunset. The LED fog light are colese to halogen but it tends to be K with brighter light footage to prevent accidents.
The yellow fog light help drivers navigate the road in snow, raining, foggy days. Yellow lights can improve the unclear situation of the road ahead, provide a high-brightness scattered light source, penetrate the thick fog, and remind the driver on the opposite side.
Nowdays, heavy fog is a major obstacle to traffic. The fog lights are used frequently when we encounter heavy fog. The yellow light has a strong scattering effect, which can make the light beam spread forward as much as possible into a large light cluster. It has a strong brightness to illuminates the road ahead for the driver and indicates their location. Yellow fog enables oncoming vehicles and pedestrians to evade through the thick fog to prevent collision accidents. Comparing the yellow lights and white lights, the yellow lights are the only light colors most drive can withstand in the fog.
We could barely see in extreme conditions and constantly needed to use yellow fog light. The LED fog light is one of the most durable and economical choices. Although it could be more expensive, they compensate for their price with their energy-efficient capabilities.
The halogen lamp has a low color temperature, a yellowish light, and good penetration, suitable for use in rainy and foggy weather. However, their dim light output and low life expectancy make their frequent replacement.
Check the halogen socket. Make sure which specific bulb size your vehicle needs. You can check the owner’s manual or search for it online, such as Sylvania, or Philips.
Consider the cooling system. There are hundreds of LED bulb brands out there, and it seems like each one designs its LED bulb a little differently. One of the most important aspects of a LED bulb is the cooling system. You want to be aware of what the most effective type of cooling system is, so you can purchase a great LED bulb for your vehicle.
Choose more durable lights. No matter how cheap the fog light, it's annoying in multiple attempts and having to return the bulbs, or change the bulb at very short times. So the quality of the lights should be at the top of the consideration factors.
It's a very multifaceted question based on your daily driving condition. The yellow fog light allows you to see further and clearer during foggy, snowy, or rainy weather, and reduces the chances of accidents. However, the white fog light can match the look of white LED lights.
It depends on your location or where you are going to visit. In general, yellow, amber, and white are both legal across the United States. But the dangerous fog light, built with red, blue, or other colors can be hazardous. It is illegal in many states.
Ease of contact with the human eye. The yellow light allows the driver to detect an oncoming vehicle with its fog lights on as soon as possible.
Much more safety. Under the illumination of yellow light, the driver will unconsciously improve concentration to avoid accidents.
Good appearance. The yellow lights add extra beauty to the vehicle. Very stylish and personalized.
Not be sufficiently bright in some situations. This will no be a big problem by adding extra lightings, such as LED light bar, pod light, white forward light, or the switchback mode fog light coming with dual color light.
Bright and straightforwardness. It's easier to see around dark corners, especially at night.
Too bright. The white light produces more glare. White light is brighter than the yellow one, however, the brightness is not the factor in every situation.
Danger in low visibility weather. The white light is not as effective as the yellow light as it has a shorter wavelength. Staring constantly at white light can frustrate the eye.
"One of them being the ease of the install and no extra wiring or ballasts needed. Also for the longevity of the bulbs. I was replacing the halogen bulbs constantly it feels like. They also were dull and didn’t provide the light output I wanted. The LEDs have a quick response when turned on and don’t need a few seconds to warm up like HIDs."
*From Josh Maldonado who completely unsatisfied with the stock light output from the headlights and fogs.
"Lack of light on the road, Having an all black car and the yellow lights really pop and looks perfect with it. I can now see much further ahead and won’t have to worry about wild life or obstructions on the road again!"
*From Tristan Johns who decided to upgrade her fog lights because he noticed he was not getting a sufficient amount of light with the stock halogen bulbs
