A soldering iron, some solder, heatshrink tubing and a half hour were all it took – oh I forgot the multimeter I used to confirm which wire was the ground wire in the bike”s system – it was indeed the green wire.
The turn flashers are brighter than they appear here when viewed from the side but I used flash for this photo and it makes the flasher seem less bright than it is. Viewed from the riders position, they are bright enough to remind me that the turn signal is working but not at all distracting.
