CUTTING-EDGE LED CHIP TECHNOLOGY: We challenge you to find another bulb on the market that produces as much light as the V.4 while still retaining a perfect beam pattern! The H4 / 9003 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 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 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.
DIMMING: The 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 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.
OPTIONAL ACCESSORIES: Even though these bulbs are designed to be plug-and-play, some makes and models require additional accessories to complete the installation. Many vehicles do not need anything additional while others may need one or all of these accessories. You can try the LED bulbs without any of these accessories and add them later if needed.
ANTI-FLICKERS: If your vehicle has PWM (Pulse Width Modulation) or CanBus, you may experience flickering, shutting off, or errors on the dashboard once you install the LED bulbs. This is an easy fix, simply add our anti-flicker cancellers to prevent any issues caused by PWM or CanBus. These plug directly between the LED bulbs and your factory harness. If your headlamps have a dust cap, you will drop these inside of the housing before you install the bulbs.
BULB ADAPTERS: When you remove your stock halogen bulbs, if there is a metal or plastic adapter that locks the bulbs into place, you will most likely not be able to reuse it for the LED bulbs. However, we have a wide selection of aftermarket LED Bulb Adapters that will replace your stock model.
RUBBER DUST CAPS: If your factory housing dust cap will no longer fit your headlamp due to the rear section of the LED bulbs is too large, you will need to replace it with aftermarket LED Housing Dust Caps. You can measure the opening of your housing to select the exact size you need or select the universal model which can be trimmed down to the size you need.
