Have an 80 with the old school Bosch quad headlamp set up. The two outer ones functions as the low beams with the two inner ones kicking in when you turn on the high beams.
I pulled out the high beam bulbs and saw that they were also H4's with a low beam filament. My headlamp lenses were also the same for all four units.
So I went to Jemson and had him fiddle with some wires so I could have 4 low beams and 4 high beams.
And here's the result (don't mind the different hues). Outer lamps are Circuit brand all weather bulbs, inner lamps are some old yellow bulbs I found lying around. Nothing final yet, still playing around with the bulbs (no plans to go HID or anything exotic).
The wiring and sockets are also upgraded to handle 100/90watt bulbs.
They have also done this mod to a Shark Galant.
Will work on cars with four H4 headlamps. No glare to oncoming traffic since the beam pattern is still low beam. So far, my electrical system is doing ok at least according to my voltmeter.
