Re: One More Headlight Relay Thread
Outstanding write-up, TR!

Love the pictures with captions and your schematic. I am a huge fan of H-4s, and have used them for years. They are definately a "must-have" upgrade for any old vehicle.

Thanks Chevy!

So, will this be the next mod to the '65 ??

Chief, The E-code lamps and H4 Hella's work so well I have put that on the back burner, way back.

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.
I have always wondered why these were not this way factory. does anybody know? you have four lights why not have them on?

Without relays the amps would be around 40, with the four lamps on, too much for the switch, and too much for the old generators and alternators. with a modern alternator and relays, should be no problem.
