S-V.4 LED 9005 / 9145 High Beams Bulbs (Pair)

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 to 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 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 housing.

Thermal Management: The S-V.4 LED bulbs are built from the highest quality 6063 aluminum material originally designed for aircraft and spacecraft applications. This material has amazing heat dissipation qualities as well as is 100% corrosion resistance 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 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 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.
