When does money outweigh sentimental value? 1968 notchback build thread

I added mine to try to keep from getting rear ended. People now are accustomed to the third brake light and ‘68 Barracuda brake lights are on the small side and not overly bright. When leaving car shows in the evening it always bothers me that some of these beautiful older cars have very small and somewhat dim rear lights. Some of them cars are even hard to see from behind depending on color.
My glass guy is supposed to come next Saturday to install the windshield. I'm gonna have him throw in the back glass as well. Then I'd can start third brake lite mock up. Hopefully 1 of the 2 workout. They are both LEDs. Actually I don't have an incandescent bulb in the whole car.
