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.

I picked up a full volt using the relays. Be sure to use heavy enough power wire.

Good diagram too.

I did the same thing, but in "stealth mode." I have a 1-wire alternator, so I gutted the voltage regulator and stuck the relays in there.

My testing, using my Nikon's light meter, showed that the low beams increased by 100% in intensity and the high beams increased by ~66%.
