Re: 12 Volt Relays in a 6 Volt System

Generally 12v relays require a 12v trigger source to switch.

I would think that Taillights would not require a relay as they are not pulling the same type of load that lets say headlights or a horn is. Turn signals are already relayed by virtue of the turn signal flasher.

The headlight relays have merit as it keeps the high load off of the headlight switch contacts, this helps to extend the life of the switch, and it most cases gives you brighter headlights because of lowered resistance.
