didn't, you will seriously kill the expected life span.

Nope, the LED's he is talking about are designed to operate in a 12
VDC system, i.e., with system voltages as high as, probably, 15 VDC. I
initially built voltage regulators into the light fixtures I built
using the same 30 LED tubes. Bad! Dim lights. Then I had a closer look
at the "tubes". The LED's are wired in series parallel with resisters
for each series section to limit current Flow. You just plug them in..

Yep, they are dang near idiot proof. They'll take the full range of
battery voltage. The G4 variety with the warm white LEDs are AC-DC;
just connect the two leads and pay no heed to polarity.

Clearly this is the best money I've spent in a long time...and partly
the reason I came back to this group to tell.
