Product Description
Adding fog lights where there is no factory wiring? This harness makes backlit Stage Series pods work like OEM fogs. Tie the activation wire to your parking lights or low beams and the fogs come on automatically whenever that circuit is live and the switch is on, then shut off when you hit the high beams. A separate backlight wire lets the pod backlights run with your running lights, and you can use a factory auxiliary switch in place of the included toggle.
Fitment Notes
- Built for Diode Dynamics Stage Series LED pods with backlight (DT 4-pin connectors)
- Safely powers up to 10A of fog lights
- Requires basic wiring to a parking light or low beam signal, the high beam circuit and a fused 12V source
- Check local laws for proper fog light activation and deactivation
