Unlike the OEM lights the top mounting tabs on CrystalEyes are removable and held by two screws. The tabs should've been included with the lights when you bought them.
If I leave my parking lights on when I turn the ignition off the U-bars will go on next time I turn the ignition on again. Low beams do not have to be on at all so I can essentially run the U-bars only (or together with fog lights). Contemplating whether I want to have them on automatically when the ignition is on - how do you wire that it, any write-ups?
I also did not have to "massage" anything - they fit like a glove, might be another specific of USDM models
