Ultima Lights.--Operation and Theory Info Needed
Discussion
When we were bench testing the lights prior to installation, we didn't pay much attention to the headlights, except for the fact that they worked when switches were pulled and rocked.
Now that the lights are installed in the car, and working, for the benefit of myself,and other builders here in the colonies, we need some explanation of their operation, mainly to be sure that the wiring is correct. They are wired correctly according to the instruction in the manual, and the schematic that I created from opening up the Ultima loom.
What in the UK is termed running lights, we call them parking lights. Those are the small lights that are in the upper outside headlight, and they illuminate when the rocker switch is moved to the center position.
When the rocker switch is moved all the way to what we call "low beam" position, the "parking light" stays on, and the upper-inner light comes on. When the "dip" switch is pressed, the lighting goes into the mode we call "high beam" which we use to piss off oncoming traffic when we forget to turn them off. When in this mode, the "parking light stays on, and the upper and lower outside lights come on. Both upper lights appear to just have plain lenses, while the lower outside light has a design in the lense.
Any response to the theory of the lights, and to whether they are operating properly would be appreciated.
Should have the license plates for the car early next week, so it's just up to me now.
Thanks All
Jack.

First switch position is side or parking lights, which stay on, through all other switch positions.
Next position gives dip or low beam as you say on the upper inner light. My light only has a single filament bulb and the loom does not include the blue/white wire shown on the diagram. Yours may be different. This lamp will most likely have a flat top to the beam and will point into the side of the road. The unit has 2 screws in the back which if loosened will allow you to twist the unit so it now dips on the other side. (Those going to Le Mans take note).
The high beam is as you say, both the outer lights. The lower one with the pattern in the lens is again to direct the beam but as a fan.
When on high beam I think you should end up with the dip beam still on lighting the curb (not sure if this stays on) the lower lamp fan beam lighting the middle distance and the top lamp the far distant. (and pissing of other motorists).

MY LIGHT IS ALSO A SINGLE FILAMENT. THE EXTRA WIRE IS THERE, BUT IS NOT USED.
