Update on lighting wiring, from having to look at a late-ish model Ford Mondeo recently. This has got to be the most diabolical and convoluted system ever devised!

The lighting switch is rotary on the dash and has four positions. One position clockwise from off gives parking/tail lights and fully clockwise turns on the headlights, although these will only work when the ignition is on. The parking light setting gives dim low-beam headlights when the ignition is on.

The park/tail lights stay on when the key is turned back to accessory, but switching off and removing the key results in no lights at all.

To leave the car with parking lights on, you have to turn the light switch to the extra position, counterclockwise from off. But if you then put the key back in and turn it to the accessory position, the lights go out again!

Talk about taking a simple system and making it needlessly complicated to use. [Linked Image]
