2003-2006 GMC Sierra LED Fog Light Bulbs: Looking for upgraded LED Fog Light Bulbs from a reputable brand and value the fact that we've actually tested them on your truck? Our HR Tested kits include all the right components to ensure perfect fit, function, and performance from the upgrade. At Headlight Revolution, we do 2003-2006 GMC Sierra LED lighting upgrades better!

SOLD AS A PAIR OF BULBS (this price gets you 2 LED bulbs).

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 headlight 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 headlight 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 headlight or fog light housing.

Thermal Management: The S-V.4 LED headlight 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 headlight 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 headlight bulbs that use a fan-based active cooling system are known for not being small or easy to fit inside headlight 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 headlight housings comfortably.

CANBUS Compliant: Do your LED headlight 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 headlight filament to determine of your bulbs are operating properly. Simply put, when you install an LED headlight 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 headlight 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 headlights: 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 headlight bulbs will cast a precise light beam that will give you increased visibility, a wider viewing angle, and a much longer Limited Lifetime over conventional halogen bulbs.

The S-V.4: comes in every popular style to replace any headlight 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 headlight bulb and replace bulb for bulb. Fits all applications including projectors, and headlights with dust shield covers.

Very bright!


Beam pattern is back!

by -

My usual amazon LED's really let me down my new 2011 GMC sierra. These headlights were able to rotate and give me a proper beam pattern. Excellent lights.

This is by far the best beam output I've ever seen! I was also impressed by the quality of the units, versus other brands. Very well made and easy installation. I can see very well now at night, I'm not blinding everyone with a wide scattered pattern anymore, and these bulbs are adjustable to get a perfect beam pattern. Happy customer!!


Very happy with these headlights,

Very happy with these headlights, easy install and very bright!


White light

by -

White light is nice but not nearly as bright as expected.


Great lamps

by -

First impression is that these lamps are good quality and very bright with great color index. I hope they will last long enough to be worth the cost. My truck likes to eat halogen lamps, so time will tell the truth.


Super way cool

by -

So much brighter than stock. Took some effort to get the bulb out on my 2012 gmc sierra, washer bottle and a bracket in the way, had to cut the bracket off.
