Upgrading 1965 Barracuda brake lights

I checked with the sign shop, and that reflective material is an Avery product, currently used on road signs. It does seem to excite rather than simply reflect - I will have to test it with a meter.

Have to play with whatever else is out there. The sign shop has some 3M tape with a pattern in it, but it is not wide enough to cut complete rings from. Thanks for the input.

Cycloaliphatic epoxy is great stuff, but between the cure cycle & cost it has a limited production use. The heat distortion temp for the stuff I used is 140c - and around 150c you would think it was rubber. But it returns to shape & hardness if you let it cool back down. I have seen this epoxy exposed to full sun here in the desert (used in the manufacturing of PV cells) for a decade or more. It never seems to yellow, but if left underwater for a couple of years it will get cloudy on the surface.

Probably true about the state changes, I forget how stupid the drivers are here - but get reminded every day on the way home. I believe their average IQ is their hat size + shoe size / 2

As far as bright license plates - I drive reasonably, have not had a ticket in 25 years. Our plates are blue / white flat plastic. I will take advantage of the so called "white" led wavelengths by pointing some right at the plate.
