Help with Dual Headlight Harness

[dwcsr]

Two beams on for low and 4 for high
On the 58-59 trucks they used a single beam and a dual beam headlight. Meaning that the single beam was only for high beam and the dual was a high and low beam. Single beam was a single filament and dual beam was a dual filament, so you would have the low with only two lights on and high with four lights on. Look at this diagram from AAW it shows how they are wired .
