An idea: use free pins of the microcontroller to control some board that controls an RGB LED bar.
The LED bar sequence of flash/dimming/colors could be implemented on the firmware.

I would suggest using WS2812/WS2811 or WS2801 Strips / Pixels
they need only 1 / 2 Pins + VCC/GND and are pretty cheap.
As an enhancement we could also add a Brake Light / Indicator with ~3Leds running at 50% brightness normally and when braking is detected it goes up to 100%

Yeah, I really like the brake light from KingSong EUCs.
I didn't know that cheap RGB LEDs - great!! Cheap and modular is really important for DIY.
