Many Toyota vehicles will have a switched ground that doesn't allow Holley's RetroBright headlights to work right out of the box, however Holley has a solution--RetroBright ground switched harnesses.

Each harness is designed to switch the ground back, then the headlights can be plugged into the harness, allowing you to enjoy the safety and beauty of RetroBright LED lighting. Installation is easy and effective as there is no special cutting or major reconfiguration of the factory wiring necessary.
