Design
Our 4th gen GMC Sierra PRO-series projector headlights represent the pinnacle of design and functionality for your 4th generation Sierra truck, drawing inspiration from the refined appearance of the 2016 facelift Sierra models.
Featuring a single dual-beam projector configuration, these headlights are optimized for both low and high beam illumination, ensuring superior visibility in all driving conditions. To enhance the modern aesthetic of your 4th gen GMC Sierra, we've integrated a LED light tube surrounding the projector, complemented by three LED strips adjacent to the projector to serve as vibrant daytime running lights (DRL).
The LED light tube illuminates in crisp white for the DRL function, providing enhanced visibility and a distinctive appearance during daytime driving. Additionally, the sequential turn signal function, rendered in amber LED, ensures clear communication of your intentions to other motorists on the road, enhancing safety and visibility.
Despite their advanced features, our 4th gen GMC Sierra PRO-series projector headlights remain compatible with the existing electrical system of your 4th gen Sierra. They utilize a single H7 halogen bulb for both low and high beam functions, simplifying installation and maintenance while delivering reliable and efficient performance.
Elevate the style and functionality of your GMC Sierra with our 4th gen GMC Sierra PRO-series projector headlights, offering premium design, advanced lighting technology, and unmatched performance for your driving needs.

Headlights Technology
Experience affordability without compromising on quality with AlphaRex's PRO-Series headlights. Featuring halogen light bulbs, these 4th gen GMC Sierra PRO-Series Headlights offer a cost-effective option while retaining our signature design aesthetic. Although the output may be dimmer compared to our LUXX-Series and NOVA-Series headlights, the flexibility to customize with different bulbs remains unmatched. Embrace our unique design language with the PRO-Series, offering a budget-friendly alternative without compromising on style.
As our entry-level series, the PRO-Series offers essential lighting features like DRL and blinking turn signals. However, for those seeking advanced features such as activation lights, sequential turn signals, selectable white or amber DRL, and premium LED light output, the LUXX-Series and NOVA-Series are the ideal choices.

Lens
Crafted from high-quality polycarbonate plastic, our 4th gen GMC Sierra PRO-Series Headlights are designed to withstand extreme weather conditions while delivering exceptional lighting performance. To ensure optimal light output in all conditions, we apply a layer of anti-fog agent to the headlight lens, reducing the risk of fogging and improving visibility. Additionally, we apply another coating to the lens that protects against yellowing and oxidation, keeping your headlights looking like new for longer. Choose our 4th gen GMC Sierra PRO-Series Headlights for your 4th gen GMC Sierra and enjoy reliable, high-performance lighting that can withstand even the toughest weather conditions.

Breathing Vents
Preventing condensation in headlights is a common challenge for both OEM and aftermarket products. Despite good seals, moisture can still accumulate inside due to temperature fluctuations. To combat this, we utilize Nitto Denko TEMISH® CAPSEAL™ air vents, facilitating efficient moisture discharge for our 4th gen GMC Sierra PRO-Series Headlights. These vents enhance airflow within the headlights, allowing moisture to escape more easily, akin to a breathing action, earning them the moniker "Air Breathers."
