Time for an upgrade! From the factory, the GMC Sierra has LED accents in the headlight that illuminate in a white color, for the parking light and DRL. Diode Dynamics replacement LED boards add a brighter DRL and additional amber turn signal for a custom, yet functional look. Your order includes two sets of LED boards, one for each side of the vehicle. 

Switchback. These LED boards are a direct replacement for the factory ones, but have double the number of LEDs. They illuminate white for your parking lights and DRLs, with a dimmed power level at night. Anytime you hit your turn signal, they light up in a brilliant amber that is even brighter to indicate signaling. While the amber is extremely bright, we do not recommend disabling your factory turn signal. 

OEM-grade design. At Diode Dynamics, we work directly from OEM data, and use a 3D scanner, to develop precise replacement boards with identical mounting points and shape. Just remove the original boards, and ours will fit directly in place with correct alignment. You'll also see OEM design features, such as high-intensity automotive emitters, wire connectors, and serial numbers for quality assurance.

Optically correct. Unlike strips or halos, replacement boards work in conjunction with factory optics in your headlight. Since the factory setup uses only one white chip, it can be difficult to align the light properly from both replacement emitters. To save cost, other brands often use low-cost generic chips, which cannot focus light properly. This creates odd appearances, as some sections are brighter than others. Diode Dynamics uses high-intensity automotive emitters to direct light properly to the factory optic, and all designs are tested a number of times with small adjustments to make sure the setup is optimized. Even a 0.1mm change can make a big difference, and Diode Dynamics products are carefully tuned for maximum performance.

Reliable operation. To drive the high-power LEDs safely, a constant-current, waterproof, inductive driver is included for each set. These drivers were designed to last the life of your vehicle, and have been subjected to advanced transient voltage testing. These tests replicate the electrical wear and tear experienced in automotive environments every time your alternator starts and stops, which is what kills less robust electronics over time. The entire kit is also tested for long-term operation from -40 to 185 degrees F, vibration, and corrosion. All of these tests are completed to SAE/DOT standards, just like the factory components.

Note: These boards are not compatible with aftermarket (non-factory) headlamps.
