Am I right that that the son rear light should only be piggy backed off the front light, or run with the voltage protection cabling if running direct off the dyno?
Depends on what voltage protection it has built-in. Some (maybe most) rear lights are fine on their own, some burn out very quickly. SON’s website is rather sparse on information.
