Re: [AMC-List] headlights

Incorrect!

A four-headlight system is designed to operate as follows (this is true for all manufacturers I can think of):
horizontal arrangement: two outer lamps are low/high beam and two inner lamps are high beam only--this means that on low beam operation only the two OUTER bulbs should be in use. On high beam, ALL FOUR of the lamps should be on.
Vertical arrangement: Two upper lamps are low/high beam and two lower lamps are high beam only. Two uppers on with low beam only, all four on with high beam. 

In the late 80s GM played with this a bit with their really small sealed beams (think 1988-89 Silverados and 86-89 Centuries, etc), in which case the outside lamps went off with high beam and the two inner bulbs operated only.

IIRC, four headlight systems use all four lights only on dim, so
actually draw more power on dim than bright (55x4=220W; 18A@12V). When
on high beam the inboard lights (dim only) go out (60x2=120W; 10A@12V). 
Of course placement of the filament in the bulb (reflector) and aiming
has a great affect on lighting.
