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.

9004 Installation in '92 Jaguar XJS
The V.4 is of quality construction, but the installation in the '92 XJS is not simple as one must reach through a removable panel in the splash shield just forward of each front wheel. It is an installation pretty much by feel, as one cannot have his arm in the hole and see what he is doing at the same time even if there were a light in the area at the same time. The left side went pretty well as the .V.4 removable collar indexed into the hole as easily as the halogen bulb that was removed, and the retaining ring locked in place properly. The right side was a different story and the collar did not seem to index into the back of the headliamp as it should and did on the left side. The halogen bulb did not seem to have any problem indexing and going in. I initially thought the three slots on the collar were not wide enough or not indexed properly. But widening those three slots a bit still did not work. I then considered removing the headlight assembly and started to do that. It became apparent that was not the way to go as the process was more complicated than needed - in typical Jaguar British fashion. So, back to the previous method. I carefully examined the collar and determined which slot on the ring should be at the top. I carefully inserted it that way and wiggled it around until it seemed to catch a bit - not the same feel as the left side or the incandescent bulb. I felt (remember I cannot see in there) around the edges at the back and it seemed to be inserted evenly. the retaining ring locked into place correctly. The car's electrical harness for the headlight is quite short, and getting two hands into the hole male the connection of the cars plug and the V.4 plug a bit of a challenge. Big hands forget it. Haven't had a chance to drive it yet or adjust the pattern at night but the brightness is impressive.
Best headlight ever
Bought these for my 92 mustang. Love them
One of the units had
One of the units had defective high beam. Promptly replaced.

Charles J. Husted Inc.
6 months old one quit on high beam. Calling support now but i know its impossible to get someone
