The turn signal switch is in the top of each steering lever. Using the toggle switch there is very convenient location and I can still rest my hands on on top of the levers without triggering the signals. The first switch is power on/off the next two control the headlights and the last one with the two LEDs above it is the running lights and turn signals. To prolong battery life I can turn parts of the system off. Turning on left and right signal lights is like having hazard lights.
Just behind the seat on the bar supporting the rear fender is the battery. Before I had the battery sitting on the floor but this is a better location. The battery comes in a small pouch with a Velcro strap that makes hanging it here easy. There would be room on the bar for at least three other battery packs.
This Milan does not have all lights the production version will have. The rear light and brake light will normally be added into the back edge of velo below the rear handle. The problem with adding them to this one is that I can't get inside to bond them in place without cutting a large hole in the bottom of the shell. It is impossible to reach the back edge once the shell is assembled and the rear fender is in place. They will have to be added before the top is bonded to the bottom. The only other bits missing are the covers that go over the chain under and behind the seat. Moulds for these are made but they need sanding and polishing.
