  • 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.



These fog light bulbs: are YELLOW color output, and have the SAME 3,600 lumen of light output per bulb as the S-V.4 fog light bulbs.

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! And 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.

Huge Improvement Over The Stock Halogens!


Bulbs seem to be high quality, and installed fairly easily in stock 2016 Ford F350 fog lamp housings. These are way brighter than the stock halogen bulbs, even though they are yellow. What I'm most impressed with is the controlled beam pattern. It has a nice cutoff, and works great in snow, fog, and rain. I highly recommend these.


Perfect set up

The yellow is consistent and the aim is perfect . It blends with the headlights quite well for a good balance of light down the road and close. They're bright enough that I can almost use them alone ( if they were aimed higher) . Quality bulb , clean and clear patter.

These were exactly what i was looking


Great lighting.

Highly recommended.


Didn't fit right!

Trying to make the one on the right side fit, it wouldn't go in and the plastic receiver part broke a piece off then it fit and sealed snugly with the LEDS pointing to the left and right. The left one didn't fit either but instead of breaking the receiver as the right one did I clipped a portion of the plastic receiver on the back of the reflector housing and got it to fit snugly but it didn't clock the LEDs exactly Lft & Rt so I will have to go back and adjust it a bit to clock it correctly if it beams much differently than the right side. They are super bright about 3 times brighter than the crummy stock ones.

I got the Amber version. These penetrate fog very well and tend to make road signs light up as if you hit them with a green laser, which is pretty awesome. I live in a rural area, so nobody complains about amber bulbs, but your mileage may vary.
These are installed on a set of IPCW reflector housings in a 90's GM truck for high-beams. Because these are amber, there are some quirks to be aware of.
1: When you shut the lights off, you don't get the "sudden dark" sensation as much.
2: The physics of using yellow light are different from white light. 6000K White will allow all colors to reflect back to you, giving you the illusion of a brighter light. When you go to amber, you are illuminating a specific color. That means shiny objects, yellow, and white will reflect back at you, while everything else is black. Blue looks green. Green sometimes looks blue, other times looks green anyway.

3: I am using S-V.4 Perfect Fit in my low-beams, so I do have white light available for legal reasons. Both bulbs have the leads necessary to get the polarity correct, and the adjustments to get them properly aimed in the reflectors.

These are EXCELLENT products. The light output is on-par with my Ryobi P717 LED spotlight. That device has a tighter reflector in it, so it ultimately throws further, but normal headlights look like candles compared to that thing.


Great light output
