The GMC Sierra is a great truck for many reasons, such as: its range of engine options, smooth and comfortable ride and its spacious and well-equipped cabin. Other reasons include its variety of trim packages and high towing capacity which is why we have a lot of customers who like to modify their Sierras with off road lighting.

Included with this product is a full wiring harness which consist of the following:

• Light Switch: CE Compliant 3 Pin Rocker switch encompassed in a water-proof housing. A red power indicator light will illuminate when the light is on, which is bright enough to be seen during the day but dim enough so it will not cause a distraction when the light bar is powered on at night.
• Relay: 4 pin water resistant relay is rated for 12 volts and 40 amps. The relay also includes a heavy-duty mount allowing for multiple mounting locations. 
• In-Line Fuse: Industry standard blade-type fuse encased in a water-resistant
• Wire: Is wrapped in extra thick thermoplastic insulation. The terminal ends are soldered and insulated in heat shrink tubing to prevent contamination from foreign materials. A rugged PVC encases the wires for a very professional looking installation. 
  • Wiring Lengths: Aurora provides you with a total of 16 feet of wiring.
  • From the relay, you will have eight feet of wiring to the LED Light bar, four feet of wiring to the on/off switch, and four feet of wiring to the battery.
• Deutsch Connectors: The Deutsch connector has a thermoplastic housing design that is sealed to the elements with its signature integrated latch. The integrated latch wedges the terminal pins together in order to create an impenetrable seal eliminating the likelihood of moisture intrusion.

Terminal Ends: To ensure a seamless connection to your vehicle’s battery, the positive and negative battery terminal cables are equipped with soldered ring terminals covered with heat shrink tubing.

Illuminate Your Adventures: Why You Should Consider a Light Bar for Your GMC Sierra

The GMC Sierra is a powerful truck capable of tackling various terrains and tasks. But when nighttime or low-light conditions hit, even the brightest stock headlights might not be enough. That's where a strategically placed LED light bar can make a big difference. Here's why you should consider adding one to your Sierra:

Enhanced Visibility:

• Off-road adventures: Whether you're exploring trails, camping under the stars, or navigating backroads, a light bar casts a powerful beam, illuminating obstacles and terrain you might miss with headlights alone. This translates to increased safety and confidence while venturing off the beaten path.

• Work zones and low-light tasks: If your job involves working outdoors at night or in poorly lit areas, a light bar provides ample illumination for repairs, loading/unloading equipment, or general visibility.

Safety and Awareness:

• Improved nighttime driving: Additional lighting enhances your ability to see potential hazards on the road ahead, giving you more reaction time. This is especially crucial on rural roads or highways with minimal streetlights.

• Increased daytime visibility: While not as impactful as at night, a light bar can improve your daytime visibility in foggy, dusty, or rainy conditions, making your Sierra more noticeable to other drivers.

Customization and Style:

• Variety of options: Lexbern Light bars come in various lengths, configurations (spot, flood, combo beams), and mounting options, allowing you to tailor them to your specific needs and aesthetic preferences.

• Rugged and durable: Aurora Light Bars are built to withstand harsh weather conditions and off-road terrains, adding a touch of functionality and style to your Sierra.

Important Considerations:

• Local regulations: Ensure your chosen light bar complies with local laws regarding light output, placement, and usage.

• Professional installation: While some light bars are easier to install yourself, complex wiring might require a professional's expertise for optimal performance and safety. Luckily all Aurora and Lexbern light bars are e4asy to install. 

• Responsible use: Remember, excessive light can be blinding for oncoming drivers. Use your light bar responsibly and only when necessary.

Ultimately, the decision to add a light bar to your GMC Sierra depends on your individual needs and driving habits. If you frequently encounter low-light situations, enjoy off-road adventures, or prioritize safety and visibility, a light bar can be a worthwhile investment. However, carefully consider all factors and choose a setup that complies with regulations and promotes responsible driving.
