re: "Hook them up the other way and in about two seconds you'll get a
flash and a small amount of smoke being let out of the bulb."
That doesn't make sense. LEDs are diodes ("light emitting") and when
reverse-biased will just block current flow; i.e. nothing will happen
(they won't light up). If their rated voltage is exceeded--presumably,
they're rated for 12V or more--they'll be destroyed regardless of which
way they're wired. Maybe there's other components in these kits that
could fry if reverse-biased, but a diode won't (if the diodes are 5V
there's probably some resistors to reduce voltage, but resistors don't
care which way the current is going).
If they're in a socket plug--like a bulb--then just switching the
internal leads for ground and power--if it's possible to get to
them--would allow them to work in a pos. ground car (as long as there's
nothing else 'hot' that could be grounded).
Happy Thanksgiving all,
