Product Details

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.

2015 gmc sierra


Horrible projection head lights from gm. Installed the new S-V.4 v4 led. Clocking the lamp was simple. Results are unbelievable, actually have a cut off line and the road is now well lit. Thanks HR for providing information and knowledge to make a confident decision on best way to upgrade projection headlights.

S-V.4 v.3


Great bulbs. Excellent beam pattern. Tight fit in 2010 Tucson Headlight fixture. Best way to install in a Tucson is to remove headlight fixture [ 5 minutes ] then it's a lot easier to install the bulbs. Replace fixture [ 5 minutes ] in all 20 minutes for a good upgrade. A bit getting used to the white light, but excellent illumination of the road. Headlight Revolution gave me help in deciding which bulbs would be best, through email. Thanks Guys

S-V.4 H4


I searched for info re. LED heaelights and the most unbiased and informative videos on youtube were from this company. On that basis I bought these S-V.4 H4s. I`ve used these on my outer, dipped, headlights on an `84 Ford Capri (I`m in England) - what a result! I`d tried cheaper LED H1s in another unit and they were terrible: blurred cut off, light everywhere, these are in another league. Crisp cut off, excellent light distribution, and the colour is just pure white. It`s like switching on daylight! I worried about the authenticity on a `classic` car - but they`re so damn good.... I`m never going back! .

Great Headlight (minor gripe)


Very bright. Easy installation. I would give them 4.5 stars out of five except for one minor gripe. Installation documentation is minimal. It's possible to align them either verically or horizontally and I had to go to the internet to figure out the proper orientation or alignment. Great lamp otherwise.

As good as stock but brighter


I do like it and i already tried the v.4
And its no different except of it is brighter and a there is a very minimal glare above beam pattern not sure why

The only downside i see is that adjustable collar which is not so firm when you put it into housing and the dust cover and pushing agaist it
I did like the old fixed collar

I can see!!!!.


These are great bulbs. Put them in a 2005 Honda Element. The Leds are facing 3 & 9 o'clock positions and my wife now understands the benefits to Leds. Her quote "I can see!". The lights are very bright but we leveled the bulbs and no issues with on coming drivers. These are literally a like night and day comparing them to Halogen to Leds.

2017 Tundra Crewmax Limited


Easily the best LED bulb I have tried. Near perfect beam pattern. The high beams actually work. Nice and bright too! The bulbs are easy to install, but make sure they are perfectly vertical to get a sharp cut off.

Love them!


I love these bulbs! They are super bright and you can clearly see the beam pattern. TheyÄôre not scattered at all. I had Opt-7Äôs on my FJ Cruiser and the passengerÄôs side bulb became really dim and were scattered. Not the case with these! I also had the OPT-7Äôs on my Ram 1500 and because of the CANBUS system, I always had the low beam out message. It was so annoying! The wiring also melted within 3 months and when I contact OPT-7 (and finally got a hold of them) they could careless and said it was not their problem that my truck almost caught on fire. My local Dodge dealership recommended Headlight Revolution and I could not have been happier! Their customer service is above and beyond. They have helped me every step of the way with the ordering process and when I ordered the wrong bulb size and caught it before the item shipped, they exchanged it for me with no problems and no additional charges. They have gained a loyal customer! I am a service advisor at a dealership and when my customers are looking for aftermarket bulbs, I always direct them to Headlight Revolution. Keep up the great work! :)
