Guide "PowerBeam"s were the OEM bulbs used from 1973 to 1980, for both low and high beams. In 81, Chevrolet replaced the PowerBeam high beam bulbs with Wagner Halogens, while low beams continued to be regular Guide PowerBeams or sometimes regular Sylvania bulbs were used.
The PowerBeams have not been made in years and are not being repro-ed. I don't know what the actual numbers are, but the common numbers for a round 4 bulb system are 4000 for the lows and 4001 for the high beams.
