Our 2002 Dutch Star came with DRL's (Daytime Running Lights), I removed the relay since I didn't like the DRL's and they confused truck drivers who seemed to think I was giving them the clear to pull over signal. Got run off the road twice before I disabled them and never since!
They still come one when I turn on the windshield wipers and stay on till I turn the ignition off, the switch won't turn them off one the wipers have started.
