I have a question, I was hoping someone could answer here. I have searched the internet with no luck. We have a 2015 Kia Optima EX. My wife has always left the headlights in Auto and she swears, that there was a daytime running light present on the car. I don't know which light it was though. I am pretty sure that one was illuminated before also. So we had to take the car to the shop for one of the automatic fold up mirrors, that decided it didn't want to fold up anymore. She actually asked the tech which light was supposed to illuminate as the DRL because I was going to just change the bulb. They told her that the car did not have DRL's. So, are we crazy or does something on the front of this car function as a DRL. I thought possibly the low beam bulb was using a dual filament and running one filament for the DRL and the other for the actual headlight, but the bulb looks to be a single filament. Could it have been the fog/driving lights were on and that was what we always seen?
