I have DRL's as an 'installed' option (car was a rental car prior to my owning):Does anybody have a full run down of what turning DRL on does in a stock configuration?
Sounds like it uses the Low beams. Does it use only a portion of the power or full power? When to they turn on? (Car on? ebrake off? in gear?) Does turning the dial to off turn them off - aka they only work when dial is in "Auto" mode?
-It uses the low beams at an even lower setting during the day (my best guess is about 60-70% power) and the tail lights at a similar level
-They are always on when the car is on, even when the dial is set to off or parking.
-When it gets dark enough, they are only available at standard low beam brightness
