So here we go...I apologize for the pictures not being very easy to determine which light is on since I did take them just a minute ago when it was light out. Not sure why the photo sizes are all over the place either.
with the stalk in the on position, all lights are on.
With the switch in what I understand as the parking light mode, both of the the orange corner lights are on.
With the switch in the DRL mode, no lights are on.
And with the switch on off...self explanitory. I have not noticed a difference when the parking brake was on in any of the lighting modes..
