Fleece Performance 07.5-24 Chevrolet Silverado/GMC Sierra 2500HD All Lights On

One Plug-In Module Activates All Three GM Light Circuits That the Factory Shuts Off on High Beam

The Fleece Performance FPE-ALO All Lights On module plugs into the factory fuse box on 2007.5-2024 GM trucks and SUVs, enabling the high beams, low beams, and fog lights to operate simultaneously when high beams are switched on. The FPE-ALO requires no wire cutting, no relay installation, and no custom harness work. It connects at a single fuse box location and works with the factory lamp circuit on Silverado HD, Sierra HD, Silverado 1500, Sierra 1500, Suburban, Tahoe, Yukon, Avalanche, Colorado, Canyon, and other GM platforms covered by the same fuse box connector configuration.

All Fleece products are engineered and assembled in the USA.

Frequently Asked Questions

The FPE-ALO simultaneously activates the high beams, low beams, and fog lights on compatible 2007.5-2024 GM trucks and SUVs whenever the driver switches the high beams on. From the factory, GM vehicles turn off the low beams and fog lights when high beams are activated. The FPE-ALO bypasses this without any permanent wiring changes.

No. The FPE-ALO is a plug-in module that connects at a single factory fuse box location. No wires are cut, no relays are added, and no harness fabrication is required for installation.

The FPE-GM-ALO-37 is designed for the 2004.5-2007 GM Duramax LLY and LBZ fuse box configuration only. The FPE-ALO covers the newer 2007.5-2024 GM platforms (GMT900 and K2) across a much broader range of GM trucks and SUVs including 1500 series trucks and large SUVs.

The FPE-ALO covers 2007.5-2024 Chevrolet Silverado 1500/2500HD/3500HD, GMC Sierra 1500/2500HD/3500HD, Chevrolet Suburban, Tahoe, Avalanche, GMC Yukon, Yukon XL, Chevrolet Colorado, and GMC Canyon, among other GM platforms sharing the same fuse box connector interface. Verify your specific model year against the Fleece compatibility list before ordering.

Yes. The FPE-ALO is fully reversible. Unplug the module from the fuse box and the factory lighting behavior returns to stock with no modification to the vehicle's electrical system.

Running additional lamp circuits simultaneously increases heat output and electrical load on the bulb sockets. Bulb life may be modestly reduced compared to standard factory use patterns. The circuit operates within factory design tolerances.

Fleece lists 2024 GM trucks as covered by the FPE-ALO for applications where the factory fuse box connector interface is unchanged. Confirm with Fleece Performance directly if you have a 2024 model, as late-production vehicles occasionally incorporate mid-cycle engineering changes.

The FPE-ALO is a lighting module and its function is independent of the engine type. It works on GM trucks and SUVs with the compatible fuse box connector regardless of whether the vehicle has a Duramax diesel, gasoline V8, or other engine.

Installation Instructions

1. Confirm your GM truck or SUV is within the 2007.5-2024 coverage range and has the compatible fuse box connector described in the FPE-ALO instructions.
2. Locate the factory fuse box in the cab as directed in the included instruction sheet.
3. Identify the target fuse box connector.
4. Plug the FPE-ALO module into the designated fuse box connector location.
5. Test by turning on the headlights, then switching to high beam and verifying all three light circuits activate simultaneously.
