I used a flat carbon fiber plate, 2,5mm thick and cutted i so it fitted to the upper tail section.
With rivets, i added mounted points.
The number plated is fitted by an aluminium striope, which is attached from inside the tail for cleaner appearance.
The lights are street legal LED which are made by Shinyo, modell STRIPE.
The are 20 Euros each, so roughly $25 each
The turn signals are yellow or clear, the rear light (with brake inducation) is clear, black or red.
I cutted wholes in the uopper tail (very carefully, only one chance) and bonded the LEDs with a automotive adhasive.
By using a 5 wire cable and a 3 pin an a 2 pin AMP superseal plug. I was able to make it easy to disassemble the upper tail fast.
There is a LiIon battery (700 gramms) installed.
