Playing with WS2812b LED's to simulate turnsignals and emergency flashers

Based on adafruit neopixel library. simple logic. code is crude but functional. just 4 swiches with pulldown resistors and a strip of ws2812 tape 8 led's long with a 470 ohm resistor in series with the data line between the Arduino and the first LED.  I was able to power it through the USB port no problem.
