Upgrading 1965 Barracuda brake lights

Nice work! Thoughtful and knowledgeable configuration makes all the difference -- smart design of the 3-segment drivers, heat sinks, etc. This works; "LED bulbs" and other such junk doesn't. Guess you have already seen the intensity and ratio info in this thread. What grade of retroreflective sheeting did you use for your new aft reflectors?

Also curious to know more about your lens casting technique and material.
