quad headlight change out

[piecesparts]

Has anyone performed the upgrade of the mid 80s truck quad headlights to the lights that take bulbs in the back of them? I am working on that very task and have come up against an interesting thing. With the top lights changed out, the lower lights (High Beams) come on dim, when the low beams are selected (turned on). It appears that there may be a lack of ground circuit or not enough resistance in the low beams to keep the high beams from being illuminated. Can anyone let me know if you experienced this and what did you do to solve it? I have not put in a pair of relays and wiring harnesses, but that is what I will work on tomorrow.
