Looks good!
That small LED tail light will be woefully inadequate.
I had a similar one on my Cafe' build, and in sunlight and daylight it is not visible......nobody in their car/truck will see your brake light come on. While it may appear adequate in your garage or driveway when you are looking directly at it - when it is out on the street in traffic it will not get the attention of distracted drivers.
I added a red emergency flasher module that can emit light steady without flashing as a brake light - it is far more visible. It is very bright and I put some red electrical tape on the lens to limit the brightness a bit so it is not overly bright and blinding people after dark - you could also use an electrical resistor.
I used this light for a brake light:
