Signal lights don't come on with DRL's, but when you turn your headlights on there is a difference in the color of light between the headlights and the (now white) signal lights. It might bother you. I never see it because I'm always driving the car, so it doesn't bother me. If you don't change to a new blinker module the blinkers (all 4) will blink about twice as fast as normal. That looks very wrong to me. I don't notice any difference with the remote lock/unlock blink.
