NJSBYL All Lights Mod 6 Hi plug-and-play module for Chevy/GMC/Buick — fogs, lows and highs together, OEM connectors

The NJSBYL All Lights Mod 6 Hi is a plug-and-play module that enables high beams, low beams and fog lights to illuminate together on compatible GM trucks and SUVs for improved forward visibility.

This compact electronic module installs in minutes between the factory connector and the BCM socket to allow fog and low beams to remain on when the high beams are activated. It’s built for specific Chevrolet, GMC and Buick models and uses OEM-style connectors and automotive-grade wiring so installation does not alter the vehicle’s original wiring or appearance.

Will this module work with my Chevy, GMC or Buick model?

The NJSBYL 6 Hi mod fits a defined range of GM vehicles—primarily mid-2010s to early-2020s Chevy, GMC and Buick trucks and SUVs. Confirm model year and variant before purchase to ensure compatibility.

• Compatible models include: Chevy Silverado 1500 (2014–2021), Silverado 2500HD/3500HD (2015–2023), Tahoe (2015–2020), Suburban (2015–2020), Equinox (2010–2019).
• Also fits GMC Yukon/Yukon XL (2015–2020), Sierra 1500 (2014–2021), Sierra 2500HD/3500HD (2015–2023), Terrain (2010–2017).
• Includes Buick Envision 2016–2019 support.
• Verify presence/absence of IntelliBeam before installing (see next question).

How does it behave with IntelliBeam and automatic high-beam systems?

This module does not operate in tandem with GM’s IntelliBeam automatic high-beam control. If your vehicle uses IntelliBeam, the fog light activation rule changes: in IntelliBeam mode the fog lights will not turn on with the high beams.

• Manual high-beam activation: fogs, lows and highs illuminate together.
• IntelliBeam active: fog lights remain off when IntelliBeam controls highs.
• Recommendation: disable IntelliBeam if you want consistent all-on behavior.

What benefits will I notice after installing the all-lights mod?

The primary advantage is increased forward illumination and better visual coverage in low-light and poor-weather conditions because fogs, lows and highs operate together. The change is immediate once the module is connected and does not require custom wiring or programming.

• Brighter, more even forward lighting when high beams are on.
• Improved visibility on dark roads and during adverse weather.
• No vehicle appearance changes; OEM connectors preserve factory look.
• Durable construction for long-term stable electrical connections.

How difficult is installation and what comes in the package?

Installation is plug-and-play and typically takes under five minutes: you insert the module between the factory harness and the BCM socket without cutting or splicing wires. The unit ships ready to install and includes customer support if you need guidance.

• Simple insertion between factory connector and BCM—no modifications required.
• Uses OEM-style connectors and automotive-grade wiring for reliability.
• Package contains one NJSBYL Headlight All-on Mod and installation assistance.
• Compatible with existing factory headlight components and bulbs.

Who is this for: The NJSBYL All Lights Mod 6 Hi is designed for owners of compatible Chevy, GMC and Buick trucks and SUVs who want a straightforward, reversible way to boost night-time forward lighting without changing headlamp hardware. It’s ideal for drivers who frequently travel on dark rural roads, encounter poor weather, or prefer fuller illumination when manually switching to high beams. Avoid this module if your vehicle’s IntelliBeam automatic high-beam system must remain enabled and you expect fog lights to follow IntelliBeam behavior.
