With many options available, which are the best fog lights? From halogens to HIDs and LEDs, we’re going to answer that question right now.

Best Fog Lights

Fog lights come in various types from the factory. The main types you’ll find are:

  • HID (white, yellow, or blue)
  • LED (white or blue)
  • Halogen (white, yellow, or blue)

#1 – HID Fog Lights: Kensun HID Fog Light Bulb

For those that are looking for maximum performance and longevity, HIDs are your absolute best choice. HIDs provide more light output than any other type of bulb on the market, with the exception of some LEDs (LEDs have some other downsides).

Kensun has taken our top spot for the best fog lights for many reasons. They have become one of the top-selling brands in the HID headlight space. They sell both HID replacement bulbs as well as HID conversion kits, which you’ll need if your vehicle comes equipped with halogens from the factory.

This particular bulb comes in 10 different color options, including yellow (3000K). So if you want yellow fog lights, these will give you the most intense yellow light available.

HIDs just plain out-perform halogen bulbs, hands down. It’s better technology, period. They’re much brighter than halogens, and the service life of an HID bulb is typically longer than that of a high-performance halogen bulb.

#2 – LED Fog Lights: OPT7 LED Fog Lights

OPT7 has emerged as the leader in replacement LED headlight bulbs and is number two on our best fog lights list. Their LED conversion kit provides many size options and produces a bright white light color. These LED bulbs produce a light color that looks very similar to HIDs, with some minor differences.

LED headlights or fog light bulbs have single LEDs that are mounted to the sides of the housing. Therefore, the light output may not be perfectly intense at 360 degrees, unlike HID, which accomplishes this well.

The major upside to LEDs is the service life. At 50,000 hours, you’ll never find anything else that comes close to lasting as long as these do.

Even with that slight downside, these are some of the brightest LED headlights available. Excellent choice for anyone looking for bright white light and long service life.

#3 – Yellow Fog Lights: PIAA Plasma Ion Crystal Yellow

PIAA Plasma Ion Crystal Yellow

These yellow bulbs have received 4.6 stars out of 5, and PIAA is a very good and trusted brand anyway. If you are in the market for yellow halogen headlights, I suggest you consider these. These will give you that euro look and discharge a very yellow light.

You can’t go wrong with these. These are an OEM direct replacement for your vehicle, so there would be no modification to install these. Just make sure you purchase the correct bulb that fits your vehicle, as not all bulb connectors are the same.

#4 – Yellow Fog Lights: Nokya Arctic Yellow Bulb

Nokya Arctic Yellow 9005 Fog Light Bulb

These currently have a 4.4 out of 5-star rating on Amazon.com. These will also give you the yellow fog light look that you’re looking for, but they’re also not very expensive (around $10 for a pair).

Both will give you a color temperature of 2500k, which is well into the yellow spectrum. As you consider the two brands, PIAA is well known and well established, and that is primarily what you are paying for with the added cost.

Their construction is likely better as well. Nokya is not a bad brand, but their’s is not as widespread and well known as PIAA, hence the lower price. It’s likely that you’ll be happy with either bulb.

#5 – Blue Halogen Fog Lights: Sylvania SilverStar zXe

Sylvania 9006 SZ SilverStar zXe fog lights

Sylvania bulbs will be higher on the color temperature scale than most halogen bulbs; however, they will likely be close to white, with a slight blue tint.

If you’re going to go blue, staying lower on the temperature scale will increase visibility while keeping that blueish look. If you’re going to a deep blue, don’t buy these.

As a second option, consider going with some LEDs. LEDs put off a very intense light and look a lot like an HID bulb, but you won’t have to modify anything to use them. No conversion kits are required.

Although they look bright, they don’t throw the light very well. Down-road visibility is limited, but they look great, and to some, especially since fog lights are secondary light, that’s OK.

Yellow Fog Lights, Are They Really Better in the Fog?

For many years people believed that because yellow light has a relatively long wavelength, it would be less refracted by the moisture in the air, allowing the driver to see further in fog. I think we’ve all experienced driving in the fog or snow and turning on our high beams, and it becomes difficult to see.

That’s because the light is being refracted and scattered across the molecules in the air. Although yellow light indeed has a relatively long wavelength, it isn’t very important when dealing with particles the size of rain, snow, and fog.

In other words, it doesn’t really do anything. And actually, if you’re going to go the scientific route, red light has the longest wavelength, so we should all be driving around in the fog with red fog lights, right? Wrong.

I don’t know about you, but I’d be awfully confused when I saw red lights coming at me through the fog. It’s likely that it would look like someone was traveling in reverse.

Now that we have that out of the way, why are yellow fog lights still around? Because yellow fog lights look awesome! If people want them, then car manufacturers and after-market parts companies will keep making them.

Another very interesting fact is that the light that is most visible to the human eye is the color temperature of 5800K. Or, in other words, the color of the light that is radiated by the sun. Imagine that.

So you’ve got t choice to make. Do you go for visibility from the driver’s seat, or do you go for what looks cool from the outside? There is no right answer. The fact is that yellow light isn’t bad for the eye. It’s just not ideal.

So the compromise is minimal. If you’re going for visibility at night and in the fog, look for a bulb that will put out light at the color temperature of about 5500K. You’ll find that most of the high-performance bulbs will accomplish this for you.

The cheaper, standard OEM replacement light bulbs will emit a color temperature of about 3500to 4500 K. See below as a reference:

Blue Fog Lights, Are they Worth the Vanity?

Based on the light color chart above, blue lights are a little tougher for the eye to see. Depending on just how blue you go will determine how difficult it will be to see at night.

Will blue light help you see better in fog? No, Blue has a short wavelength and is at the opposite end of the spectrum from yellow and red. Blue could be one of the worst foglight colors you could choose for your fog lights.

Once again, you’ve got a choice to make. If you live in an area that rarely sees any fog, like where I live, you’ve got nothing to worry about. However, if fog is a part of your daily routine, then I’d steer clear of blue fog lights.

I’d rather make it through than look good when it comes to fog. If you like the look of blue light, I’d suggest you go with a slight blue, like a bulb that emits a color temperature of about 7000K. Anything past that might be a little too blue, making it tough to see.

HID vs Halogen Fog Lights

halogen vs hid fog light

HID, or high-intensity discharge, fog lights, or any headlights for that matter, will almost always emit more light than a halogen bulb and look better doing it (in my opinion). There are many fog light bulbs out there that try to mimic the look and color of HID bulbs, and from where I’m sitting, they’re left wanting.

HID fog lights are ideal, and if your vehicle is already equipped with them, great, but if it’s not, all is not lost. There are many HID fog light kits out there that will convert your existing halogen setup to an HID bulb set up, so it can be done.

However, be aware that the headlight housings are not all created equal. In other words, headlights built to take a halogen bulb in many states will produce a lot of glare for oncoming traffic, making it illegal.

If you are going to install an HID conversion kit on your vehicle, I suggest you take some time to do some research surrounding the laws in your state regarding HID conversion kits. There’s nothing like spending money on a kit, just having to spend more money on a ticket, then revert back to halogens anyway.

If your vehicle was built for halogens, there is a way to install an HID conversion kit legally. That way is also to install new headlight or fog light housings that include the proper projector, or you can retrofit your current housing with something like this:

projector headlight fog light

The projector is that glass eye-looking thing that you see in many high-end vehicles. The projector controls the high-intensity light being emitted by the HID bulb and keeps it from glaring in the faces of oncoming traffic. This is the right way to install an HID conversion kit on your vehicle. You should not have to worry about getting a ticket if you have used a projector in your headlight housing.

One major downside to HIDs is that they are more expensive than a halogen bulb. HID bulbs will outperform most halogen bulbs, but you will pay extra for the added performance. Although, generally, HID bulbs will outlast a halogen bulb, especially the high-performance halogen bulbs.

In doing some research on the longevity of halogen bulbs vs. HID, HID bulbs will often last for 100,000 miles or more, which for many could take many years, while high-performance halogen bulbs will only last about 10,000 to 20,000 miles, depending on how much they are used.

These days, many vehicles always have their headlights on as long as the vehicle is running, which will wear out the bulbs quicker. The good news is that fog lights do not fall in that category, so you’re likely to see them last much longer.

If you’re going to simplicity, just stick with the bulb type that your car is made for. However, if you’re looking for the added performance and improved appearance that an HID bulb brings, then get a set of projector lenses and go HID. You won’t be disappointed.

The Clear (or Yellow) Fog Light Winner(s)

So what is the best fog light? The answer is… it depends on what you want. However, consider the purpose of fog lights (to help you see better in the fog) and the color temperatures that are the easiest for the human eye to see (around 5500K). The champion would have to go to the Sylvania D1S High-Intensity Discharge (HID) Fog Light Bulb.

It’s the right color (5000K), it lasts the longest (some HIDs have been known to last the life of the vehicle), it puts out more light than its halogen competitors, and it’s made by one of the most trusted and leading automotive lighting manufacturers around.

The only downside is that most vehicles are not equipped with HID fog lights, so as a close second and a personal favorite, the PIAA Plasma Ion Crystal Yellow fog light bulbs are the clear (no pun intended) winners of this comprehensive comparison. But I’m a sucker for yellow fog lights. What’s your preference?
