Description

The Z-Flash LCM 2500 is the latest evolution in the Z-Flash product line, delivering a plug-and-play GM light control solution engineered for 2024+ GM and EV vehicles. Supported platforms include the Chevy Silverado EV, GMC Sierra EV, 2025 Chevy Tahoe, GMC Yukon Denali, and GMC Sierra HD3500 Denali.

Designed to integrate directly with the OEM Light Control Module (LCM) beside the BCM, this advanced GM light controller allows users to flash factory-installed lights in up to seven selectable flash patterns, including two new inverted flash modes for improved visibility and emergency signaling.

Flash pattern selection is controlled using the factory high-beam lever, maintaining full OEM functionality. The system can also be activated via the included push button, upfitter wire trigger, or the OEM keyfob, making it ideal for fleet vehicles, emergency response, utility trucks, and EV applications.

The Z-Flash LCM 2500 is fully backward-compatible, providing a seamless upgrade path while reinforcing Ultra Bright Lightz’s commitment to reliable, vehicle-specific fleet lighting control solutions for modern GM gas and electric vehicles.
