I installed the Motodynamic Integrated Tail Light last night. It is a beast to pull the rear tail light from these. Takes maybe 10 minutes to pull the tail off, but that rear light is literally wedged in there. You have to pry it out using screwdrivers, all the while hoping you don't crack the paint, or even the plastic. When I checked it before putting it together I checked that the blinkers and brake lights worked, but I didnt check to make sure the headlight and tail light functions worked. Got everything together and well they dont work now. I am guessing I blew a fuse, but the main one was still in tact, so I will dig through it tonight again. I also may have just pinched a wire, but I don't know yet.
