Bring professional emergency-vehicle capability to your new GM truck or SUV with the ZW-GMLCv2 Light Controller Module (ZWAGZ). This innovative, plug-and-play unit connects directly to your OEM GM Light Control Module and allows you to flash your factory lights with a simple press of a button or using your OEM controls.

Designed for 2021–2025 GM vehicles, the GMLCv2 gives police, public-safety, and fleet users three powerful flash patterns—each selectable right from your high-beam lever.
