Add fog lights to your vehicle. If you want to add fog lights to your vehicle, but you don't have factory wiring, this is the solution you need! Unlike other basic harnesses on the market, our Add-On Fog Harness allows your fog lights to operate automatically, just like you'd expect from the factory. By using an activation and deactivation wire, along with a toggle switch, this harness will turn your fog lights on automatically any time the headlights are turned on, and the switch is in the on position. This is much more convenient than manually flipping a switch on every time you want to use them!

This harness is intended to be used with Diode Dynamics Stage Series LED Pods without backlight functionality, and can safely provide up to 10A of power.

Wiring. We recommend connecting the Activation Input Wire to your sidemarker or low beam signal, so your fog lights can automatically turn on with your parking lights or low beams. Any time this activation signal is powered and the fog light switch is in the On state, the fog lights will be turned on.

  • Allows you to add fog lights to your vehicle with factory-like operation.
  • Dual Deutsch DT 2-pin output connectors.
  • Compatible with non-backlit Stage Series lighting products.
  • High-capacity 16AWG wiring and 15A waterproof fuse.
  • Works with factory-installed auxiliary switches.

Free Canadian shipping on qualifying orders $399+, with no duties or brokerage. Special order and made-to-order items can't be cancelled or refunded once ordered. Oversized items may have a handling fee depending on your location; pickup in Mississauga has no fee.
