Reading through this thread there seem to be some rather confusing statements.
No one seems to have addressed the issue of AC v DC.
I very much doubt your bike runs on AC. It may well have an alternator, but the alternator will be configured to produce a unidirectional output.
If the power is truly AC then discussion about 12V v 13 V v 14 volts is fatuous.
Secondly LED is short for light emitting diode. A diode is another word for rectifier.
So an LED specified for 12v will operate perfectly happily on 12v AC, 12v DC or 12volts unidirectional output from an alternator.
The voltage spec for any diode/rectifier is known as the peak inverse voltage PIV and describes the maximum reverse (off) voltage the diode can block. The forward (on) voltage is defined by the diode and will be around a couple to a few volts.
The current in the on mode needs to be set (limited) by an external component as the diode cannot do this for itself. However I would imagine your tail cluster contains such components.
