Saw this old 57 Chevy taillight on the ebay, thought it would make a cool conversion project. Wrote a fade-to-black code for 16 segment neopixel (fades 250x250, dark red to white, max brightness about 150) Second led is white for reverse light. momentary push-button for 'on' triggers a 555 looping timer circuit using a 2200 uF cap for about 40 min of on-time. This 555 analogue 'countdown' circuit does not use any power in the 'off' position and basically feeds itself through a 5v reed relay for as long as the 2200uF cap has power. When off, no drain on battery pack. A second parallel 5v reed relay triggers the trinket.
3D printed the battery/circuit box. Also has inner removable radio-shack 6v battery box with it's own on/off switch.
Cleaned up the chevy taillight and mounted to wood base. Cool little project....maybe a kid's nightlight..
