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.

FJ Cruiser Headlight upgrade!

Mark Gennaro

The lights are super bright. I do have a problem with the high beams shinning to high. Not sure if it's because I have a 2 inch leveling kit or not. The low beams work great though.

Purchased the bulbs for my 2013 Honda Ridgeline. They have improved my vision at night. The actual installation was easy once I figured out how to do it using a variety of YouTube videos.

Dark Alaskan Winters

Ben Griess

These lights fit just as advertised on my 04 Tacoma, perfect. Great beam pattern, super bright, and doesnÄôt blind oncoming traffic (when properly adjusted). I was hesitant because the cost but well worth it. Was going to install a light bar before I got the lights, but after I got the new lights installed, the high beams do the job so now I donÄôt have mount anything extra.

Really bright and great beam pattern

Jeff Cunningham

These gems fit right in my 2002 TacomaÄôs stock headlights. Even with the fogged plastic lens covers, theyÄôre several times brighter. Took me a min to figure out I had to rotate the bulbs to get the best pattern.

IÄôm somewhat skeptical that the stock rubber caps on the back that cover the end of the bulb and the connection canÄôt be used anymore due to the cooking fins and the bulb fan. IÄôm thinking their purpose was to keep out dirt, grit and water. IÄôll need to keep checking the fins and fan to make sure they donÄôt collect crap.

All in all, IÄôm really impressed so far. The stock halogens, even the brightest aftermarket, were horribly dim and easily overdriven.

9003 v4 led bulbs 2008 highlander

Don Hval

I purchased these bulbs along with a pair of fog light and reverse light bulbs
The v4s well the one works on again off again on high
I send a email to headlight revolution twice
They answered saying did you do this did you do that take videos and pics to make sure IÄôm doing right
IÄôve a couple of ground up restoration and itÄôs not my first time working on things like this
I also just to make sure IÄôve taken it to the dealer when the bulb didnÄôt work they didnÄôt find anything wrong with the vehicle but said it something with the wire harness for the bulb
So around around we go
Sorry for the rant

Excellent upgrade


This upgrade was done to my 2010 Toyota highlander. The V4 headlights are night and day better than the stock OEM bulbs. I also own a pair of GTR LED headlightsĶ And I have to say that the V4 LED lights seem to be a little bit brighter. I would highly recommend these lights to anyone looking to improve their night vision with an easy install.

H4/9003 LED Kit

Derrick Jones

I just love the product, they give me great illumination over the stock lights thus enhancing my vision. I was using another brand before and what I found is, if I was listening to the radio and turned the lights on the audio became distorted. But not with these, no distortion at all and theyÄôre worth every penny.
