Do you need zener diodes or something to limit the DC when your motor
starts charging? The LED's are 12v and the alternator puts out 14
something, right? Do people do this for the whole panel? Thanks.

The LEDs are themselves need between 1v and 4v depending on colour,
the 12v replacement bulbs must have some sort of internal drop down.
You need to check their spec to see if they can cope with the charging
voltage, but also to see if they can deal with the spikes etc that an
alternator based 12v system can produce.
