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.

Impressed with the ease of install. Most impressed with the way the lights match the original lights pattern! While shopping for lights, I read a review where the customer complained of the fans on the lights making noise. My wife just last night complained of the same. In the review it was suggested the user lubricate with white lithium grease, I'll give that a try. Otherwise totally happy.


Really good!

These lights are bright! I've been using them for about two weeks now and have had no operational issues. My only issue with the lights is the clocking feature. I am not able to get them perfectly horizontal because of the locking screw locations. Maybe a pinch screw setup would be better.


Very bright! Highly recommended if

Very bright! Highly recommended if you need better lighting at night time!


Perfect JK stock replacement

Brighter white light with stock beam pattern and keeping the classic stock look. High beams seem different to me than stock but still good. Only issue is fitting all the extra wiring and stuff behind the housing.


Supemova V.4 LED Headlights H 13 Builbs

I purchesed this set for my Fisher snowplow headlights due to the low light that the reg builbs where giving out. I tryed this 1 much brighter & much easier to see what you are doing along with the reduced load on the battery since the plow takes a lot of power while plowing. Couldnt be more happy with the way they worked this last big storm we had in MA on 3/ 3-4 / 19 overnight they really lit up the work area !


Well worth the money!!!

I've tried all the "upgrade" halogen bulbs on the market, but nothing compares to these S-V.4 V.4 LEDs! The beam pattern is sharp and tight. No flashes from oncoming traffic. The light is intense and white. MUCH brighter than the stock halogens on my JT Gladiator. Everything was literally plug and play. They work brilliantly in my Jeep pickup. Being able to finally see along these rural, dark, curvy, deer-populated country roads is well worth the money!


S-V.4 v3 install on 2018 jeep wrangler Rubicon JL

by -

headlights fit perfectly, took a little creative arranging to get the led driver and anti flicker module to fit and get the cap closed but it can be done. customer service was very helpful when choosing which bulb and anti flicker to use as there has been absolutely no issues with this setup and they are BRIGHT! out perform the oem halogens by car!


Better than expected!

The S-V.4 4 is the third LED bulb IÄôve tried in my 2018 Nissan NV cargo van. The stock bulbs were horrible and I was ready to get HIDs but the S-V.4 has an amazing output. Nice cutoff line and they were so simple to put in. No adjustments needed. I would definitely recommend. I even got my dad to buy a pair for his truck


V.4 LED H13 bulbs

I saw HRÄôs video a while back and was impressed with the presentation on LED light in general. I recently bought a 2012 Jeep Liberty and after driving it at night I determined the stock lighting was inadequate. Even a switch to the Ultra halogens was of marginal help.
I then sent an email to Headlight Revolution and asked for a recommendation for better lighting.
Their recommendation was the S-V.4 V4Äôs. I was impressed by their videos and when payday rolled around I ordered them.
The only glitch was I ordered when they were transitioning to a new, larger warehouse and there was a delay in receiving them. IÄôm sure we both learned from that experience.
I installed the LED bulbs and was duly impressed with the improvement in night vision and response or lack of response from other motorists.
I am now looking to switch my older VolvoÄôs to LEDs along with a 77 CJ5.
In short, I love the lights!
