There have been a few of us, me included, who have blown fuses for the tail light and headlights thru removing the park bulbs when we install the led headlights. The fact is that in some of the led headlights there is no place for the park lights so we remove the bulb and shove the wiring into the back of the headlight cavity somewhere...the wedge type fitting shorts out on itself and "Pop" goes the fuse. Either put the bulb back in to stop this or cut the wires back. It does however leave an option to run "something else" off the wires and use the park position on your ignition to "liven" it up....maybe a nice led sign saying "DONT F.....G TOUCH THE BIKE!!"...be quite good at night don't you think?
