Overview. 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 with 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.

We recommend connecting the Deactivation Wire to your vehicle's high beam circuit. This will automatically disable the output any time your high beam is activated.

Finally we recommend connecting the Backlight Activation Wire to a fused 12V source to trigger the backlight feature such as the parking light or running light. Before wiring please check local laws and regulations for proper activation and deactivation of the type of lamp you are powering with this harness.

Auxiliary switch compatible. If your vehicle came with a factory-installed auxiliary switch bank you can use one of them as your fog light switch instead of the toggle switch that's included. Simply connect an Auxiliary Switch output to the harness using the included Power Input Wire.

Allows you to add fog lights to your vehicle with factory-like operation

protection plan is easy.
The protection plan worked on my coffee pot. It was just over 14 months and started to leak. I first called amazon and they sent me a link to the protection plan. It was very easy to use. I received a Amazon gift card instead of a replacement. The price of the coffee pot had increased so you will receive the lower option. I did receive the total cost of the pot at the time I purchased it.

It is worth purchasing a Protection Plan on an unfamiliar item
Bought a 3-year protection plan for a nut milk maker machine for $5.99. It was a fairly new kitchen item in our household and we were not familiar with the brand. So, I bought the plan for a piece (peace) of mind. The machine worked nicely for about 18-20 months with daily use until it tripped the circuit outlet. My initial chat with Asurion did not go as I expected due to discrepancy on their end as they see a protection plan for the nut milk maker as a sporting goods valued between $100-$199, not as a kitchen item valued between $30-$39.99. ( I had bought 3 different protection plan on th same day for multiple items purchased on Prime Days). They were looking at a different plan and I was unable to get them to "scroll over" to the appropriate protection plan. I tried again on a different day during the first hour of their contact hours and had a cheerful Asurion agent who was able to find the appropriate kitchen item protection plan. It was a simple and thorough conversation and transaction. I was refunded within hours after I packed up and dropped off the damaged item out to UPS. Moral of the story: Asurion Protection Plan is worth it and contact them at the start of their first day shift, not at the end of their evening shift.
