  2. Forgot to say my question is about 3mm/5mm LEDs, not big, powerful LED
    bulbs!

  3. Quote from that website:

    Short circuits Mechanical stresses, high currents, and corrosive
    environment can lead to formation of whiskers, causing short circuits.

    Doesn't smell like normal use.

    Well, high currents can ensue if you fail to use a current-limiter of
    some sort; this includes the cheapest possible current limiter: a resistor.

    Corrosive environment includes ones with oxygen.

    Mechanical stresses includes any place which might have vibrations,
    which is almost anywhere.

    Normal use shouldn't smell. If it smells, it's likely you've forgotten
    to limit the current ;-).

  6. I suspect few, including me, would ever actually see a LED dying
    normally. The equipment might have been upgraded or replaced before that. :)

  7. Since it's just a toy circuit, it would not happen. The DC in would not
    fluctuate much, I suspect....
    Not for my toy, could be common for real cars...
