View Full Version : Front Fog Light Switch Illuminated After Aftermarket Headlights Installed.

So I have plug and play aftermarket headlights installed with DRL. The DRL's run off the parking light circuit. There is also a normal headlight bulb, a high beam headlight bulb and a blinker.

Whenever I have the parking / headlights activated, the green light on the front fog light switch becomes illuminated even if the front fog light switch is not depressed. It's not actually a problem, but I was just wondering how does that work? considering that I don't have any fog lights in the new headlights.

My car previously had the internal fog lights in the two piece headlights (pre-facelift I believe).

I did the independent fog light mod on my car and randomly the fog lights will be on when I start the car. All of the head light electronics go to the fog light relay so it can turn off then the parking light only and high beams are on. I haven't been able to figure it out yet.
