  • 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.


Best LED

Bought these for my 2015 Dodge Durango. I've tried other less expensive LED bulbs in my Dodge V4 blew them out of the water when it came to beam pattern and brightness. Worth every penny spent. Great tech support from HL Revolution. Will definitely recommend to my friends.


Works Great

Easy to install. The only con I had with them I had to adjust the set screw and it would come loose easily making it a little more difficult to get right light pattern.

Corolla 9012, first time using led, it looks using good material. However I was not very happy with my transformation, this might be as a result of my headlight house setting

The light arrived promptly I was a little skeptical because I was stuck on ordering from Amazon all the time, these LEDs blue, Amazon's LEDs out of the water, they fit tightly and perfectly excellent customer service, excellent delivery, highly recommended.

These are good LEDÄôs, flat out. Can you get something cheaper elsewhere?... Yes. Can they match the quality and customer service though?... No. Look, these people have done their research, and their reputation precedes them. The LEDÄôs are quite bright, and mimick the OEM pattern quite well, just brighter. You can see much further down the road. The only two things I can say negative are; 1) The securing collar for the driver connection is plastic and does not tighten as well as it could (Could easily be stripped). - 2) In my particular headlight housings (Toyota halogen projectors), there is a noticeable dark spot that triangles down away from the bright focused part of the pattern (likely due to the void of light at the very bottom of the led board, where a halogen would produce that 360 degree illumination.) - To be fair, I went into the switch to LEDÄôs knowing that could be a reality. I previously had some less expensive Kensun bulbs that didnÄôt have this issue, but they also failed several times and werenÄôt as bright. - Do yourself a favor and stay away from cheap/budget LEDÄôs and buy from the folks who have already done all the trial and error for you. Easy to install in minutes if you have replaced headlights before, and assuming your vehicleÄôs bulbs are easily accessible. I also appreciated that these came in a 9012 for my vehicle, so I didnÄôt have to Äòtrim to fitÄô the mounting tabs. Pleased with the purchase and will buy again in the future. Good job HR!

Love the beam pattern and the factory cut off line is great I live in a neighborhood with no street lights and they light up perfectly at night
