My headlights are not as bright as they should be and my taillights are not very bright. I am running v-8 and running a high amp one wire alternator. Tail lights are original 51 tail lights. Help would be appreciated.

Dirty switch contacts can rob a lot of voltage before it gets to the lights. Ditto for grounds, particularly back at the tail lights. Running relays to the headlights takes a lot of load off the switches. It's very noticeable on 6 volts, but there will also be a difference with 12V headlights.
