ZW-GMLC-EV – Advanced Plug & Play OEM Light Controller for New GM and EV Models

The ZW-GMLC-EV is the latest evolution in the ZWAGZ product line — a plug-and-play OEM Light Controller module designed specifically for 2024 and newer GM and EV vehicles, including the Chevy Silverado EV, GMC Sierra EV, 2025 Chevy Tahoe, GMC Yukon Denali, and GMC Sierra HD3500 Denali.

This upgraded module connects directly at the OE Light Control Module (beside the BCM), allowing you to flash the factory lights in up to seven unique patterns — including two new inverted flash modes for enhanced visibility and customization.

All patterns are easily selectable using the factory high-beam lever. The system can also be activated via the included push button, upfitter wire trigger, or even the OEM keyfob, giving operators maximum flexibility and control in the field.

Backwards-compatible with all vehicles supported by the previous ZW-GMLCv2, the ZW-GMLC-EV continues ZZ2’s mission to deliver fast, reliable, and innovative fleet lighting solutions.
