That's an excellent idea! How much current do they draw? Incandescent headlights are 70 watts (max on high) and 50 watts (max on low), so the current on high is 140W/13.8V = 10.15 Amps for both headlights. JH1

Success! To recap, what I did was reestablish a working headlight switch. My truck was hacked before, so my solution is not universal. However, assuming you start with a standard issue setup, take the switch outputs that normally go straight to the headlights and running lights, and instead, run...

Good input, Artisan! I'm going to scrounge up a couple of 30A automotive relays and use them to send the heavy currents to the running and headlight circuits. From what I can deduce, there are two independent circuits inside that switch. One for headlights and one for running lights. The dash...

Another really odd thing happened. Can't believe it, but here's the scoop: There are 4 small 12v bulbs illuminating the 16 speed gear selector, 3 of which were burned out. The 4th one would blink. Blink? Really? Book doesn't say squat about a blinking light there. Inserted 3 new bulbs (#1831...

One thing that is easy to do and might help is to run the dash light knob all the way to full bright, instead of dim or half dim. That will eliminate the heat generated by the circular spring-like resistor. By setting it to full bright, the resistor is not in the circuit, and therefore will not...

Wow. Ok, I'll use a relay. I wonder if the blackout circuit automatically disengages if the headlights are turned on? Obviously, there's no need for them with headlights on. I'll go flip some switches and report back. Thanks, guys.

I have a M915 that someone messed with a little. The original headlight switch is long gone, and it looks like they wired in a Ford Pickup switch in it's place. It was working until a while back when it got hot and quit. All headlight current (10A) goes through it, as opposed to using a relay...
