LED Fog Light Bulbs
[ In Stock: 0 pieces ]
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.

Pretty damn good
Bought these promptly after seeing the Tundra h4 video. My wifes 2018 Honda fit low beams were excellent, as per typical for h4 bulbs. However the high beams were a scattered mess just like the Tundra h4 video. They were absolutely useless. Which is typically very uncharacteristic for most h4 housings. Once I saw the S-V.4 v.4s make a drastic difference I immediately made the order.
I installed the bulbs promptly. And was amazed with the output. Lows are not quite as even of a pool of light as the halogens, as to be be expected with the way LEDs have to be. But whats there is still very useable and more intense then stock. I did have to reaim the lights a little. The driver side light flares up a tiny bit almost like if it was a RHD unit. Weird.
High beams. Holy hell did they improve. Drastic difference with actual useable hotspots instead of scattered dim dots of light. A-freakin-mazing. I got damn good upgrade without having to do a retrofit. Im happy with them.
I only wish they had a finite rotation adjustment like Ive found with the Morimoto LEDs i installed in a friends car. That would of let me tune out that weird little flare up on the driver side.
This ate great bulbs plenty of light out put the only issue I have is I could have bought this bulb straight from S-V.4 for 109.00 a pair that's slot of savings
Installed on Honda ruckus. Had to buy another set for the H-D.
These replace a set of LED bulbs that had a fan die in one bulb. The cutoff on these are much better and do not blind oncoming traffic when in low beam. A bit of a challenge to fit the left bulb due to space restrictions but overall an easy job. Very pleased with the amount of light and overall look of the bulb
H4 on the Skoda Yeti
I basically wasted money by installing a cheap pair of LED bulbs in my vehicle. When a friend recommended these, man what a difference. The cut off was correct and they was no flare of the light output. These bulbs are great and very usable as compared to the other set i tried on my vehicle.
I am completely satisfied with this produce and the CANBUS is a must for my european vehicle. I am getting ready to purchase more bulbs.
These headlights were great and so much better than the original lights. They were easy to install and put out a lot of light. The road was easier to see as was off to the side of the road. I felt much more comfortable driving at night because I could see so much better. Unfortunately, my truck was totaled when someone cut in front of me and I lost the lights. Once I get a new truck, I will be ordering new bulbs. Customer service was also great. I wasn't sure what I needed and they were able to help me right away.
V4 led bulbs ... awesome
These made an amazing difference on my ÃÃ²96 4 runner. Total install time less than 4 minutes!!!
1996 Toyota Tacoma
I installed these bulbs along with the Vision X H6054 headlight housings in my 1996 Toyota Tacoma and boy what a night and day difference it was from the stock halogen bulbs. Install was a breeze just plug and play.
The light shape and hot spot seems to stay relatively unchanged with these. What you will notice different is the intensity of the light. These are that "just perfect" brightness where it is still insanely bright but does not glare like crazy. Worked well with the OE housing on 1st gen Honda Fit. I first installed omitting the weather seal, but thought of condensation ruining aesthetics and put it back. Fan is somewhat blocked by weather seal, which sits in front of the fan, covering flow slots. Not very hot where I live, so we will see if this allows enough airflow. If it ruins the light to run in this condition I will report back.
Great bulbs. Crisp white light with a perfect factory pattern. It's what Toyota should have installed to start with!
