However, I suspect that the cheap, thin metal contacts Ford puts into their light switches overheat, and after enough time develops corrosion on the contacts which inhibits electrical current flow [acts like a resistor].
I further suspect that the delay in time, or manually tripping on the bright lights, causes momentary increased current flow which [in a miniature way] "blasts" some of the corrosion from the contact points, allowing more current to flow, and thus the lights to come on.
Some years back I had a similar problem with the ignition/starter switch in my '89 F-150, and this [corrosion of the contact points] eventually was determined to be the cause.
In that case, the only fix was to replace the ignition switch, and I suspect that for my headlight switch, replacement may turn out to be the only "fix." I'm hoping this time the cause will be simpler, and I can make a repair as the light switch is not only expensive, but a pain in the a$$ to replace.
What else can I help you with?

Why do the brake lights on a 2000 4Runner barely come on when the headlights are turned on?
The brake lights should not come one until you step on the brakes. The tail lights should come on when the headlights are on. If they're weak, maybe there's dirt in/on the lenses or maybe the bulb is old and clouded. Change the bulbs and see if that improves things.

Your headlights would flicker when you turned on your brights Now they wont come on at all you checked your fuse and its working just fine you drive a 1997 Dodge Ram 1500?
You need to check the wires at the plug for the multifunction switch(dimmer). The wires like to break and get pulled loose at the plug. You will need to remove the trim around the steering column to access.
2003 Toyota corolla headlights come on when car is turned off how to keep the headlights off so it will not kill the battery?
I stumbled on this question doing a search. I have the same problem with my 2003 Corolla. It seems to happen only during very cold weather (below zero). The quick solution which has worked for me is to always turn the brights on (push the lever forward) when I park the car. The problem does not happen if the switch is in the brights position. Strange but true. A dealership told me that there is a "service bulletin" on this issue which details a fix involving a relay, as I recall. The shop said that the fix could run $1,000 or more, so I declined. Chris.
