LED brake lights?
Word of warning about custom LEDS in your tail lights.
If you need a replacement part it could be non existent or really expensive.
I have a magnifier light that uses LEDs, it's not working, parts are not available, I could get ICs and LEDs and Caps etc if I knew what was bad, but a replacement board would be the most likely fix. A twist in bulb is cheap and in a pinch a standard bulb could be substituted in
