Installation Process
The installation of PIT66 LED headlights is designed to be user-friendly and does not require advanced technical skills. The process is described as "plug-and-play," which means that the headlights can be connected directly to the vehicle's existing wiring without the need for modifications or additional components.
The installation instructions provided with the product emphasize the following key steps:
Remove the existing headlights: This step involves removing the factory-installed headlights from the vehicle. The process may vary slightly depending on the model and year of the truck, but it generally involves loosening or removing bolts or clips that secure the headlight assembly in place.
Prepare the wiring: Some vehicles may have a different pin configuration for the low beam, high beam, and ground connections than the ones provided with the headlights. In such cases, the user is instructed to rearrange the pins to match the vehicle's wiring harness.
Connect the wiring: The user is directed to locate the H4 9003 relay wiring harness and connect the new headlights to it. The instructions are designed to simplify this step, ensuring that the wiring is correctly connected to avoid electrical issues.
Mount the new headlights: After the wiring is connected, the user is instructed to mount the new LED headlights in the same manner as the original units. The included user instructions are described as making the assembly process more straightforward.
Test the headlights: Once installed, the user is advised to test the headlights to ensure that they are functioning properly. This includes checking all three lighting modes—daytime running light, high beam, and low beam.
The entire installation process is estimated to take approximately 15 minutes, making it suitable for users who prefer to perform the task themselves without the need for professional assistance.
Key Features and Benefits
The PIT66 LED headlights offer several features and benefits that make them a compelling upgrade for GMC truck owners.
1. Plug-and-Play Operation
The plug-and-play design of the headlights eliminates the need for complex wiring modifications or additional components. This feature is particularly beneficial for users who are not experienced in electrical work, as it simplifies the installation process and reduces the risk of errors.
2. One-Way Vents
The headlights are equipped with one-way vents that efficiently dissipate moisture accumulated inside the housing. This design helps to maintain the integrity of the headlight components and prolong their service life. The prevention of moisture buildup is critical for ensuring the long-term performance of the headlights, especially in humid or rainy conditions.
3. Three Lighting Modes
The product includes three lighting modes to accommodate different driving scenarios:
- Daytime Running Light (DRL): This mode provides a low-intensity light that is visible during daylight hours, improving the visibility of the vehicle to other drivers.
- High Beam: The high beam mode offers increased brightness and extended light throw, making it ideal for driving on unlit roads or highways.
- Low Beam: The low beam mode provides balanced lighting for normal driving conditions, ensuring adequate visibility without causing glare to oncoming traffic.
These lighting modes are designed to meet both functional and aesthetic needs, enhancing safety during nighttime driving while also adding a decorative element to the vehicle's appearance.
4. All-Weather Performance
The headlights are constructed with a pure clear polycarbonate shell and a high-performance reflector, which together provide brighter, sharper, and whiter light output. The light color is described as being closer to daylight, which improves visibility and reduces eye strain for the driver.
The design also ensures that the headlights perform reliably in all weather conditions. The combination of a PC lens and seamless melding prevents water from entering the housing, ensuring that the headlights remain operational regardless of the environment.
5. Luminosity and Visibility
The PIT66 LED headlights have a high lumen output, which is a measure of the total amount of visible light emitted by a source. The product specifications indicate that the headlights produce:
- 4500 lumens for high beam/PC
- 2800 lumens for low beam/PC
These figures suggest that the headlights provide significantly higher brightness compared to traditional halogen or xenon headlights, resulting in improved visibility and safety for the driver.
Safety and Warranty
The product comes with a 30-day money-back guarantee and a 1-year warranty, which provides users with peace of mind in case of defects or issues. The guarantee is described as being available for any reason, allowing users to return the product if they are not satisfied with its performance.
The DOT/SAE approval of the product is an important safety consideration, as it ensures that the headlights meet the legal requirements for road use. This certification is particularly relevant for users who want to ensure that their vehicle modifications are in compliance with state and federal regulations.
