Re: One More Headlight Relay Thread

Great write-up!

I built a similar relay system with Bosch relays for my '60 Olds and it made my lights brighter without changing out the bulbs. I did the same as you with heavier wire and good grounds. It takes the load off the headlight and dimmer switches and you don't get the voltage drop from the switch to the lights.
One trick I pulled on mine was putting a diode between the high and low beam input wires. With the flow going towards the low beam side. This will make the low beams stay on when you hit the high beams. Really nice when you have quad lights.
