In my opinion DRL (daytime running lights) are pointless on a white car... if you can't see my car in the day light you're blind and shouldn't be driving to begin with. how do you disable them and the system that turns headlights on automatically when its dark? i don't like the auto turn on becuase its overly sensitive and will turn on the head lights in the shade on a sunny day which kills my bulb life.
Just keep them they way they are. White or not, it's still easier to see it from a distance.
White can't be seen in the winter , I even witnessed an accident because the car couldn't be seen ... and yes the daytime running lights do help you to be seen and your bulb life is a non-issue . And if you live in Canada IT IS AGAINST THE LAW TO DISABLE THE DRL.
The daytime running light relay is located somewhere behind the glove box (my illustration isn't great). The name of it should be formed in the plastic. Find the red wire with a light blue tracer...it should be the only one that color combo. Cut and tape it back. Leave a good inch or so of wire at the relay in case you ever want to reconnect it. That should disable the DRLs. Hope this helps. God Bless!
