I kinda like it and I like the dual schottky diode setup where you can have a very dim center lens with the parking lights on and still have a bright circuit for the brakes.
You could perhaps take it a step further and add a circuit for a quick strobe when the brakes are first applied. You could also use the addressable LED strips so it runs in a direction that you have your turn signals turned to, but maybe that would be overkill.
What would be extra overkill but kinda cool, you could add a few strips of high output IR led's, then modify my LED controller so that these IR LED's would turn on over a speed of 60mph. This may blind any speed cameras trying to take a picture of your license plate.
I use similar LED strips for my gauge lighting conversions and you would think that the flexible pcb would be electrically isolated, it's really not. If you are sticking the LED's straight to body paint, you may be okay. I had a problem earlier when sticking these LED's inside a metal gauge can. For what it's worth, you may consider doing what I do, using double sided foamy tape so it isolates the LED from ground.
