Same here. I'm pretty sure I have had only one fail. Everything in the
house is LED except the bulbs in the attic (not worth the expense to
wholesale replace about 15 bulbs that are used maybe 4 hours per year).
I started converting to LED about a decade ago and had everything
migrated about eight years ago.

You must use some cheap LED bulbs.
I've been using LED bulbs in my house for about 10 years now and I've only had
one fail and it was replaced under warranty.
Actually, I've had two fail, but the second one was a DIY assembly of a ring of
LEDs and a separate driver that I used to replace a circular CFL in a ceiling
fan. Since I'd put it together myself in the first place, it was pretty simple
to replace the driver when it failed after 6-7 years.

My LED bulbs throughout the house fail about one evey month or so (ouit of
50 and not a single one has been due to the LED, but due to the voltage
regulating electronics.
A series resistor is MUCH more reliable

For fun, I just measured the current of my trailer's LED lights. At
12vdc:
brake lights: 100ma each (has 8 LEDs in each one)
tail lights: 80ma each (has 12 LEDs in each one)
side marker lights: 30ma each (has 4 LEDs in each one)
So they apparently put 4 LEDs in a series string, with a dropping
resistor or circuit to take up the rest.
Lee
Yep, for 12 volt DC systems, either three or four LEDs in series is
pretty normal. Those numbers make far more sense than the original post
in this sub-thread that said 30mA for turn and brakes.
