CommuterNT:
Sorry, I missed your post somehow and I am late responding.
My lights are hooked up such that I can have all extra lights turned off and only run the NT in standard configuration. I have a three button switch on the brake oil housing for that....
Usually, my D2s are on at low intensity with the low beams, and with high beam, D2s come on at full intensity together with the Rigid lights at full intensity. My Rigid lights are the spot version. What a difference these lights do for me driving in the dark. Admittedly, summertime in Alaska is never dark with sun still up at 11pm, but there is this time in the fall, late August and September when they show their worth.
I can see mounting the D2s up high at the mirrors, but not the Rigid as I think they weigh quite a bit.
