make your headlights twice as bright cheap!

make your headlights twice as bright
and cut down the chances of electrical fire
The headlight relay is a helpful upgrade. When I did it, I used an aftermarket relay and spliced in to the high beam and low beam wires under the
hood, to the headights. The objective is to have as little voltage drop as possible, between the battery and the lights. So that means large gauge wire to the relay(s), and tapping directly off the battery side of the solenoid. Get the headlight and dimmer switch, and all that small gauge wire connecting them, out of the headlamp circuit - the only contacts in the circuit will be the relay contacts.

even if it didnt make em brighter
it cuts out all that juice running through the switches
my antique switches got dangerously hot and i didnt want to fry em.

Yeah, headlight relays are a part of most of the aftermarket wiring kits, or at least the better ones. They should be mandatory equipment, and for the electric fuel pump, too, if that's a feature of the vehicle.
