dual headlights

[hilta]

Hi Again, Hope you don't mind me asking more questions, Ok I have the lights in, It is a HZ Sandman so it has the dual headlight front, has single pin globes in all 4 lights, I have all 4 lights working but not at the same time, the 2 outer lights come on correct, then when you put them on high, the whole 4 work until I let the dimmer stork go, then the 2 outer lights go off and the 2 inners stay on as they should, but the 2 outer ones are off. the steering wheel is off at the moment so not sure if that is effecting anything or not, hope this makes sense, any ideas what I should look at? The stork? Earth? or Relay? Cheers

The problem is not with your indicator/dimmer switch, it is with your wiring loom. You should have high and low beam in the outer two lights and the inner ones should only work on high beam. The set up you have at the moment is that the outers only work on low beam and the inners only on high beam, although you should find that the outers are actually single filament high beam lights. When you use the flasher on the indicator stalk both beams are activated but only while the stalk is pulled back. This is correct whether you have twin or single headlights, to have your lights operating correctly you need to change your outer lights to high/low beam lights and correct the wiring loom to suit. If it doesn't already have one, it is a good idea to fit a relay to operate the highbeams.

Factory HZ dual headlights only have a single filament globe in all 4 beams. The outer (low beam) is on for both low & high beam, while the inner comes on for high beam only. BTW from the factory, HZ duals already have a relay on the high beam.

You are correct Dick, this taken directly from the HZ Holden Owner Manual and I quote:

"FOUR HEADLAMP SYSTEM"
"Operating the dipper switch alternates the light beams on the outer two headlamps between low and high beam. The inner two headlamps operate only when high beam is selected."

So from that, the outer two headlamps would be double filament and the inners single. Obviously you would have to have the matching wiring loom etc and presumably any other differences between two headlamp models and four headlamp models would be built into the electrical system.
