Let me know when you get to that advertised 20 years. Take a look at some of the LED tail light markers on expensive and import cars (the long lines of LEDs). A lot of the time you see them not working in some partial fashion or not.
It’s not the LED part per se, it’s the power supply conversion (rectification) and voltage regulation parts that can still go south....again, come see me in 20 years and tell me the same thing.
I’ll be dead, but I’ll leave my kids a memo to get back to you.
