I didn’t like the look of the Lucas Style taillight mounted directly to the back of the seat. Having the taillight tipped upward looked “shade tree” to me, so made holders for both the taillight and license plate.
After seeing the license plate mount, I decided to add sides to better integrate it into the seat. I tried a bunch of ideas for blending the seat and license plate bracket together – the bottom of the seat was trimmed to expose a portion of the top frame rail all the way back to the end of the frame.
