nsautolighting Fog Lights Always On Adapter Harness | All Lights On Mod for GM SUVs

Experience All-Lights-On Versatility

Upgrade your GM SUV with the nsautolighting Fog Lights Always On Adapter Harness. This smart module keeps your fog lights, low beams, and high beams in sync when you engage the high beams, helping you navigate dark stretches with a consistent light profile. It’s designed to fit a broad range of models—from rugged Sierra and Silverado pickups to full-size Tahoe and Suburban family SUVs, and from Yukon to Equinox—delivering a cohesive, integrated lighting experience across diverse driving scenarios.

How it works

Designed for plug-and-play installation, the kit sits between the factory connector and the BCM socket. No cutting, splicing, or reprogramming is required in most cases. The goal is to address the common issue where fog lights or other exterior lamps shut off when high beams are activated, creating a more streamlined lighting behavior for nighttime driving.

Note: All-Lights On mod cannot work with IntelliBeam at the same time.

Durability meets practicality

Constructed with a rugged ABS housing, the module is built to resist corrosion and high temperatures while maintaining a compact footprint. This means a durable upgrade that blends with factory wiring and supports long-term use without frequent replacements.

In real-world driving, you may notice a smoother transition of lights when switching between modes, along with a consistently illuminated road edge in low-light conditions. Results can vary by vehicle and setup, but the upgrade is designed to be straightforward and non-invasive.

What you gain in everyday use

Think of calmer, more predictable lighting on rural highways, better visibility when exiting dark driveways, and a unified light behavior that reduces the need to manually toggle multiple lamps. While not a guarantee, many drivers report a more coherent lighting feel during night driving and in adverse conditions.

• Plug-and-play installation minimizes downtime and changes to factory wiring.
• Maintains original electrical integrity while enhancing lighting consistency.
