ZW-GMLC-EV – Plug & Play OEM Light Controller for 2024+ GM & EV Models

Upgrade your 2024+ GM and EV platform with the ZW-GMLC-EV, ZZ2’s most advanced plug-and-play OEM Light Controller yet. Built for modern fleets that demand reliability, compliance, and superior visibility, this module connects directly at the OE Light Control Module (beside the BCM) to instantly turn factory lights into a fully synchronized emergency warning system.

Designed for the newest GM/EV lineup—including the Chevy Silverado EV, GMC Sierra EV, 2025 Chevy Tahoe, GMC Yukon Denali, and GMC Sierra HD3500 Denali—this module delivers fast, clean integration with no cutting, no splicing, and no dealer programming required.

The ZW-GMLC-EV introduces seven factory-style flash patterns, including two new inverted patterns for maximum visibility and on-scene safety. Operators can quickly cycle patterns using the factory high-beam lever, an included push button, upfitter trigger wire, or even the OEM keyfob, making it the most flexible controller in the ZWAGZ lineup.

Fully backwards-compatible with all vehicles supported by the ZW-GMLCv2, this new EV-ready version continues ZZ2’s reputation for innovative, fleet-focused OEM integration.
