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.

Went on a 3 hour road trip at 4am. They worked great. seems to be well built.


Simply Amazing!

Installation was a breeze and the lux output is amazing!


IÄôve used led bulbs before,

IÄôve used led bulbs before, but these are a whole new level. IÄôve put a set in both lo and hi beams but just lo is enough to see everything. IÄôm truly impressed and now know what to get for future builds.

v4 bulbs for 2012 Cayman R with standard halogen lights

by -

Bulbs looked to have good quality build. Was relatively easy to install in minutes and was pretty bright. Definitely big difference in brightness compared to the crappy Halogen lights the Cayman had.


H4 headlights

After replacing multiple Xenon headlights, which didnÄôt last more than 6 months, I decided to give these a try. So far, they seem brighter and are easy to install, depending on the make of your vehicles. I ordered them for a 2004 Kia Sorento and a 2011 Kia Sorento. Headlight housing on the 2004 has to be removed, for easiest installation. Hopefully these will last at least a year.


S-V.4 H7 bulbs in 2007 Mazda MX-5 Miata

To fit in the MX-5 these bulbs require and adapter that HR does not sell. I don't think anybody sells one to fit exactly. I designed one for 3D printing that allowed me to install the H7's in the MX-5. I would not have gone to all the trouble if I had not done a test fit and saw how much light they put out. HR did offer to refund my purchase price and return shipping. Once I had seen the light output I didn't want to send them back. Here are links to the adapter on Thingiverse, and a couple of videos. One with light output and the other with installation details.


I am very happy with the S-V.4's. Worth the time and money.

Better Than I Dared Hope for! - Porsche Macan S.


After being dismayed by the standard halogen headlights fitted to my Porsche Macan (shame on you Porsche!) I cast around for alternatives.

Coming across the very informative uTube videos from Headlight Revolution, I took a chance and ordered a set of the V4 bulbs, and on HRÄôs recommendation the GTR Lighting PWM Interface Module, to prevent possible Canbus complications.
The kit arrived within a week of ordering (I got stung for £50 import dutyĶ) & it was clearly of very high quality. I fitted both, including the LED drivers and PWM modules, within half an hour had them fitted and working. No nasty error messages!

I finally tried the setup out on a longish night drive, and so far IÄôm delighted with the result. A perfect beam pattern, lovely white, bright light. Much better than I dared hope for.

The kit isnÄôt cheap, but then in my experience, you get what you pay for - a highly recommended conversion and excellent e-mail support from Headlight Revolution.

Five stars!

Great beam pattern for an led bulb. Happy to finally have better light output for safer nighttime driving!
