I should know this, but... There have been several problematic cases where LED lamps are installed in outdoor low-voltage (12V) lighting systems.
One LED lamp fails and all the other LED lamps on the same run fail to light. If you remove the bad LED then the others work fine.
Unlike incandescent lamps that fail as an open circuit, LED's can fail and short the circuit.
I'm assuming that the zero resistance across the bad lamp is causing a massive increase in amperage. But, doesn't the voltage stay the same? If the circuit breaker hasn't tripped and voltage is still being applied to the other lamps, why don't they work? Has the voltage dropped?
