DESCRIPTION
The Venom Trucks Auto Fog Lights Harness is a simple plug-in upgrade for compatible GMC and Chevy trucks that allows your factory fog lights to activate automatically whenever your headlights turn on.
From the factory, GM typically disables the fog lights when the high beams are activated. This harness bypasses that limitation, allowing your fog lights to stay on with your headlights and high beams for improved lighting performance and better visibility in dark driving conditions.
Once installed, you no longer have to manually turn your fog lights on every time you drive. The harness automatically triggers the fog lights with the headlights, making it a clean convenience and visibility upgrade for Silverado, Sierra, Canyon, Colorado, Yukon, Tahoe, and Suburban owners.
This kit includes the jumper harness and T-taps needed for installation. Venom Trucks provides vehicle-specific installation guidance and diagrams depending on your truck or SUV application.
