Just a few pics of my homemade tail tidy and rear light mod,light mod was from a pic on here.
I didn't do any measurements though,just started cutting and trimming till I got a result I was happy with.
Starting point
With the numberplate mount and light removed and some cutting done
Light unit trimmed down and speed clips fitted
Light unit turned upside down and slotted inside the undertray

Finished results
Just need some micro indicators to finish the job off
