  • Do I need PWM / Anti-Flicker Modules?: When using in Fog Lights: Unlikely. With low beams that double as Daytime Running Light: Likely.With high beams that double as Daytime Running Light: Likely. When the vehicle is late model American (Chrysler, Dodge, Jeep, Ford, GM): Likely.


APPLICATION: HID and LED bulbs are street legal in the USA for Fog Light use only. Not compliant with DOT / FMVSS108 and not street legal in the USA for Headlights. Legal for off-road use in Snowmobile and ATV headlights and off-road racing use only auxiliary or forward lighting. International street legality varies by country.

Note: This usage regulation is not unique to this item. All LED and HID bulbs from all other brands, regardless of marketing claims, are prohibited from street use in halogen headlights in the USA.



Cutting-Edge LED Chip Technology: We challenge you to find another bulb on the market that produces as much light as the S-V.4 while still retaining a perfect beam pattern! The S-V.4 LED fog light bulbs utilize the newest multi-core LED chip styles that feature one long crystal over the entire diode array to create a seamless light output source. Most LED fog light bulbs on the market essentially create 2, 3, 4, or 6 different light sources by stacking 2-6 different chips together in a line. The NLW1860CV2 chips are based on XD14 technology developed by CREE, this custom designed LED chip has no light gap between diodes which gives it a closer function compared to the original filament bulb, thus achieving a greater beam accuracy that works best in any fog light or fog light housing.

Thermal Management: The S-V.4 LED fog light bulbs are built from the highest quality 6063 aluminum material originally designed for aircraft and space craft applications. This material has amazing heat dissipation qualities as well as is 100% corrosion resistant in automotive applications. On the bottom of the heat sink lies a high-speed double ball bearing micro-fan that is fully submersible and waterproof! If the fan stops working, the sophisticated thermal management system inside the bulb will dim the fog light until it is safe to use. Considering that these bulbs can be up to 6x brighter than your original bulbs, even at 50% power, they will still be safe to use on the street in most situations. The heavy duty LED bulb power driver has a built in smart fan circuit that ramps up the speed of the cooling fan as necessary so it's as quiet as possible when it can be.

Compact Design: Most LED fog light bulbs that use a fan-based active cooling system are known for not being small or easy to fit inside fog light housings with a dust cover. The S-V.4 is designed to be as compact as possible. The mounting depth is 20-25mm on most bulb variants, low profile enough to fit even the most demanding of spaces! The heat sink / fan diameter is only 39mm! The LED driver on this bulb is larger than the previous generation, but it is still the right size to fit inside most fog light housings comfortably.

CANBUS Compliant: Do your LED fog light bulbs flicker, pulse, give you errors and warnings on the dash? Do they even work at all?? Chances are your vehicle employs some version of CANBUS or PWM to control the lighting functions. These complex OEM systems rely on the physical readings of your original fog light filament to determine of your bulbs are operating properly. Simply put, when you install an LED fog light bulb, that function sometime determines that the bulb is broken, or missing entirely and will cause the truck to malfunction. Sometimes this means they don't come on at all, other times they flash, and sometimes they will suddenly shut off while you're driving! All of these things are solved by the built in CANBUS integration circuit found already inside the S-V.4 LED driver. Sometimes an extra PWM module may still be necessary, but this bulb is totally plug and play on the vast majority of vehicles on the road today, even brand new models!

Dimming: The S-V.4 bulbs dim less and less bright until they turn off at 8V DC.

DRL: If the DRL function is lower than 8V DC, the bulbs will just not turn on at all. But if they use CANBUS or PWM at 12V DC they will work normally.

CANBUS: Some vehicles use CANBUS function to monitor and control your fog light and fog light bulbs. The S-V.4 has a slightly larger LED driver than normal because the CANBUS anti-flicker and anti-error circuitry is built in! No external components should be needed to install these bulbs with a CANBUS-Equipped vehicle. Easy plug and play installation. 2 year warranty.

Want your fog lights: to shine brighter and further but your current bulbs just aren't cutting it? Want to get rid of that old yellow light tint and give your ride an updated look with a cool white light beam? Look no further! These LED fog light bulbs will cast a precise light beam that will give you increased visibility, a wider viewing angle, and a much longer lifetime over conventional halogen bulbs.

The S-V.4: comes in every popular style to replace any fog light or fog light bulb. Match the bulb number of your original application (example: 9005, 9006, H4, H13, etc...) with the matching S-V.4 LED fog light bulb and replace bulb for bulb. Fits all applications including projectors, and fog lights with dust shield covers.

I am very pleased with these lights made a big difference. They are so clear don't even need high beams. I can see farther in front and to both sides than with oem. 2015 Chevy 3500 hd with projectors.


Customer Service and Products were both awesome.

Bought LED V.3 almost 2 years ago and one went out. I called to see what they could do and they told me they were still under warranty and they would replace them with the new V.4 for free. Super easy to deal with and great products.


Definitely will purchase more products

Amazing lights buy them and find out for yourself


Great headlights

These headlights are very bright and clear. They installed with no problems into my 2018 Honda Civic. They also match the led running lights pretty well.


Good light output but unreliable

I paid $ 150 for this bulbs and they didnÄôt even made it through the first year 10 months after install they failed and took almost a month and like 10 emails to get the replacement ones

Great bulb nice light but does not work for my 2015 Ram not compatible for that year


Amazing clarity and brightness for

Amazing clarity and brightness for my 2017 4Runner looks great in projector lenses


So far these bulbs are incredible


I purchased these to replace the low beams in my 2016 Camry. It took about 10 minutes to get these installed and I am honestly blown away by the performance of these bulbs. They are miles ahead of the stock halogen bulbs that I was using from the factory. Luckily the LEDs were in the perfect spot already and I didn't have to adjust them with the included allen wrench. I added some comparison pictures to the reviews. So far I have HIGHLY recommended these bulbs to everyone I know.
