As per Bill Russel. I have LEDS that have been in operation for decades. Even in blink mode.
But the failure mode is a Poisson distribution. They don't wear out.
Many failures have been the failure of the driver circuitry so the whole thing flashes or simply stops.
When the individual LEDs fail there are a few dead spots in an otherwise working light.
If the light had 20 to 100 original LEDs then a few failures make no practical effect so the light remains useful.
So if you have ten LED lights, expect one to fail within the first year. Sometimes almost immediately.
Expect a couple to fail within a couple of years.
Expect about a half to be working fine after 10 to 20 years.
And don't be surprised if one or two are still working when you are at the end of YOUR life.

The only failures I've seen are in the electronics, not the LEDs themselves. All are cases where the light started blinking on/off. These were some cheap ones from China, that our building used in the hallways. I counted 18 out of 92 failures. We replaced all of them with better ones, no failures after 2 years of continuous operation.
of the others I have, I have one that intermittently goes into the blink mode, that's all.

No one has any real idea but the ones in my calculator have been working since 1974.

Many years in practical terms, and you would have to take many factors into consideration. LED bulbs I have bought within the last two years for use in ordinary sockets (outlets) around my house claim 25,000 hours, subject to 15,000 switchings on and off.

Typical lifetime of LED's is 12-15 years. It depends on the manufacturer. Cheap junk might last 5+ to 10 years at 8 Hr/day.
Turn them on and off a lot and they will fail quicker, like traffic lights.

It is written on them, -on/off times -hours. 1 of 10-20 will fail(ure) before 20 percent of written. From 5 countries and many, same.
Maybe it is wet conditions and water condensation sometimes.

Of 5, one failed after a year, the rest on 4 years now.

I had one last about 8 months and have one that is 10 years old, one of the first. Most of your devices have LEDs and they seem to last a long time.
