They are stock OEM fog lights. They are set to run as DRLs via the country code in the ECU. They go out when the HID low beams are turned on. Once the headlights are turned on, you can turn on both the front and rear fogs to run in conjunction with the headlights with the fog light switches on the dash. Maybe I should get a sign like those Baby on Board ones that reads OEM Fogs are DRLs? Then people won't get mad at me for running my "fog" lights during the day?
And I wouldn't be caught dead in a Chrysler.
And maybe I should have specified those stupid aftermarket fogs, because that was what I was talking about. I believe that was what the poster, who originally mentioned them, was also talking about.
Make sense now?
