2007-2018 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 2007-2018 GMC Sierra LED lighting upgrades better!

Better than Ever: After nearly a decade of experience developing and refining our designs, sourcing the best quality raw materials, and gathering feedback from end-users on what makes the best LED bulb with the most effective beam pattern; We're proud of the new Ultra 2. This an LED bulb upgrade that is brighter. That has a better beam pattern. Lasts longer. Has more adjustability. And is easier to install. It sets an all-new standard for what products in their class bulbs should be, and we're proud to call it our own.

Brighter: The Ultra Series 2 bulbs from GTR Lighting utilize the best automotive grade multi-core LED chip technology to deliver ultra-bright light, in an ultra-focused beam pattern! Not only do the elec-tec automotive-grade NLW753 chips have more lumen density than popular (but now aging) options from CREE and Philips, but there's more to it. We have optimized the position of the LEDs so that once locked into the fog light, they are directly in-line with what the optics of the projector or reflector was designed for which will provide you, the driver the most useful and safe beam pattern. The collars have full rotational adjustability. Put simply: You'll see a lot more, but without producing extra glare to oncoming traffic.

More Reliable: Performance aside, these are the last LED fog light bulbs you'll ever need! After many simulations, we arrived at a heat-sink design that is not only extremely effective at keeping the body of the bulb >80C, but looks cool too. Since maintaining low operating temperatures is key to LED lifespan, we've paired that with a bearing-less fan to actively cool the heat sink as well. The housing on our LED drivers is completely potted inside too, which is only possible with expensive-to-produce die-cast housings like the one that the Ultra 2 uses. Keeping cool and all components dry is crucial, and the Ultra 2 checks all the boxes.

Better Fitment: We challenge you to find an alternative that produces the same amount of output with the same small footprint that the Ultra 2 has. Here we took a balanced approach between maximizing output and minimizing geometry so that they'll fit in every application. Too much power and an inadequate heatsink? Premature failure. Too much power and a massive heat sink? Great, but won't fit anywhere. Due to their superior optical focus they can create up to 10x more usable light than other LED bulb options even though they only produce 3,900 Lumen of light. If you're looking for the brightest option that's a sure fit, you've found it.

Best Warranty: You can hit the road knowing that you'll be backed with a Limited Lifetime warranty from here on out. If in the rare case something goes wrong, GTR Lighting will replace the product quickly.

HR Tested: Here at Headlight Revolution, we've spent the time to install and test all HR Tested products, so we know it'll work exactly as shown and right out of the box! Not only that, but we don't favor one particular brand. We just deliver the best product for the application, period. Be sure to reference our install videos for helpful tips on making the installation process quick, painless, and clear. HR Tested: We ensure fitment and function. You do the install.

Fantastic Factory Fog Light Upgrade

by -

I needed an upgrade to the foglights on my 2019 GMC 3500 HD Denali. The factory foglights were yellow and didn't project enough light to really even make a difference. Did tons of research and decided on these 3rd Gen LEDs! Super easy to install - pull the foglights out from the front of the bumper - don't try and replace from behind. Super bright with a great pattern! Ordering was easy and they were delivered in a couple of days. I couldn't be happier!


GTR 3rd gen led lights are not for projector lenses. Especially the 2014 and 2015 Silverado and Sierra.

I wish that I would have done more research. While the bulbs do seem to be brighter, there are dark spots at close to mid range. These guys have very informative videos if you do your homework. Unfortunately I did not run across the 1 video that I really needed to watch before ordering the bulbs. I wound up ordering HID bulbs to replace the LED bulbs. The GTR 3rd gen LED bulbs for the fog lights work very well, so it wasn't a total loss.

The lights are extremely brighter

The lights are extremely brighter than the OEM lights. The only complaint I have is the condensation in the fog lights. I disassembled the lights and reinstalled the lights and still have the condensation.
