    jcshipp - I have the 1989 K2500 with the same quad sealed beam headlights. I can't say that I'm having the same issue as you, but I do understand. Two of the lights are low beam and two of the lights are hi beam, and when you switch to hi beam the low beams go out, leaving only two headlights on at any given time.

    There are two upgrades that can be done without major modifications that I know of.

    First, purchase and install some clear driving lights (these are usually mounted on the bumper). These can be wired to come on with the low beam headlights, giving you four headlights on low.

    Second, there is a kit available from LMC truck that modifies the headlight switch pattern so that when you switch over to hi beams, the low beams also stay on, giving you all four lights on at once for hi beams.

    If anyone else has other suggestions, by all means please let me know.

    Good luck.

    You could always swap to clear composite lenses with the 4---hi mod and hid's... That would be your best route as far as visibility.
