The latest iteration of my #PCB to replace the tail lights in my #EV #Mustang arrived earlier from JLC. Looks like 5th times the charm. I managed to actually get this version to do something.

A little bit of coding later and I have a ‘demo’ working.

So, what’s better for nighttime/headlights-on mode? Top and bottom rows permanently on, middle section comes on for brakes? Or middle section permanently on and top and bottom come on for brakes?

Ooh, maybe they should ‘slide’ up and down. There’s 100ms here between rows. Perhaps a little slow.

Top bottom for running lights, middle might be mistaken for brake lights. Or do tri color and use amber for turn signals?

@FritzAdalis yeah, think this is the way. The top and bottom are a little more frosted so the light is more diffused.

You could put frosted plastic inside the lens if it doesn't dim it too much.

Addressable lights like ws2812 might make it easy, but I'm not sure if they'd be bright enough. I did find https://www.nhtsa.gov/sites/nhtsa.gov/files/tsf811128.pdf, which implies 31 cd might be sufficient (or at least legal in the US) but you might want at least 100 cd.

(If you've already researched this thoroughly, my apologies.)
