  • 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.


Fitment on the f150 was

by -

Fitment on the f150 was tight. I had to trim and tape my dust covers to be able to put them on after installing the bulbs.

Have only had them for about a month and so far they work great super bright and same as factory beam pattern.

I tried all kinds of different lights and not one compared to the sv4 they are so bright and on the road not in other drivers eyes very nice


Wow, just wow!

by -

I initially bought some LED H11Äôs from Amazon and was disappointed in the overall brightness and scattered beam pattern. (I returned them.) I did more research and decided on the S-V.4. They are very bright, but that would mean nothing without a clear and defined beam pattern. These bulbs really deliver on both fronts. I couldnÄôt be happier with the result.


Strong light

by -

I've had these LED bulbs in for about a month now. They are super bright! Since the collar on the bulb assembly is adjustable it makes it very easy to align them in the headlight housing to keep the correct alignment.


Tested first in fog light.

by -

Installed on 2018 honda fit sport fog lights. Very pleased with all the detail and thought put into the design. Being able to make small adjustments with them a plus. The brightness and great beam pattern is perfect. With the great experience I ordered the high and low beam headlight bulbs. Would post a picture but not sure how.


Still love them

by -

I have had the V.2, V.3, and now the V.4. These are still good and bright and by far the best. I love the fan instead of the braids.


Bright light

by -

Bright easy to adjust and install. Mistakenly ordered the wrong bulbs. Bit pricey for the quality.



by -

IÄôve tried a few and by far this is the Brightest and most accurate beam pattern IÄôve ever seen. DonÄôt waist your time on any others out there, lots of unjustified claims. It was also brighter than the GTR ultra 2 in my projector beam. Wish I had tried this one first, well worth $169.00.
Caution: the led adjusting screw & Allen key it comes with is very small & fragile. Can easily lose or become wrenched. If plug and play works for u great! Otherwise adjusting in a tight spot may be complicated


A great bulb

by -

The bulb is quality, I have to say, except for one part. The set screw for the locking ring is made from soft Chinese steel. Be very careful not to strip them out. Kinda hokey. Otherwise a great bulb. Beam pattern is the exact same as stock, good colour, pretty bright. Very happy so far.
19 Silverado.


Perfect beam pattern

by -

I was on the fence about paying a premium for headlights, but IÄôm glad I bought them. The V.4 not only exceeded my expectations they
let me enjoy and want to driving at night. IÄôm very glad I bought the V.4 and would recommend to anyone.
