Drl = safety..
It's like removing seat belts IMO.
I once T-boned an elderly woman in my '94 beater sentra back in the day, because she didn't see me coming (broad daylight) and primarily because I didn't have drls.
I wasn't at fault thank God.
I'm not sure that by you having DRL's that you wouldn't have T-Boned her! I mean if you can't see a car in broad daylight, how would lights make a difference?
Regardless, belts and lights are a huge difference. I also removed my chime of no belt on! It annoyed me to hell if I had to move the car around at home!
In Europe, DRL's are illegal so...
My Warranty is also done a long long time ago but I posted this not to start a debate on legalities but just if anyone wanted to have control of some features.
