I really don't know how long these lights will last

In America we have a new kind of red, yellow and green LED sold to
government bureaucrats as traffic signal lights. It differs from the 5
baht LEDs you buy in that it has a mean time between failures, once hung
over the street and turned on, of about 3 weeks. They must have put some
kind of magic timer in each of the LEDs in the big round panel set to a
different failure time. You pass a light and everything is lit the first 3
weeks. Then, one at a time, they start to fail as the magic timers wink
them out. After 2 months, half the LEDs in the array no longer light up.
After 3 months, they've already replaced it with the SAME STUPID CRAP the
first one was so it will run another 2 months......EXACTLY like the light
bulbs the LEDs replaced!

American engineering.....Planned Obsolesence....

Called "planned obsolesce" and in financially difficukt times useful
to keep Chinese electronic firms in business.
