Excellent. Post your results, if you don't mind.


No problem. I'm mainly interested in the power supply, since strings
of about 12 go out at a time. I want to find out if its a crappy SMPS,
ar maybe a couple to reduce the chance of catastrophic failures. Now,
all I have to do is get my hands on some samples. I may try contacting
Florida DOT. If they are rebuildable, I am looking for a few projects to
create part time jobs for local Disabled Veterans. I'll bet that they
can replace bad capacitors and LEDS after they are troubleshot.
