Question on suburban grille conversion headlight operatio

[CT-Truckster]

ok when the lights are on bright are all four lights supposed to be on or do they rotate between high and low beams? i got them wired up and they work with just low beams on low and just high beams on high, is this the correct operation? if not i need some help in wiring them if they are all four supposed to be on with high beam selection. and this is on my 84 originally with four headlight setup. thanks.
