Just so no one gets confused with low/high for the driving lights, heres whats needed.
Main headlight driving light is the H4 globe
It uses the LOW part as the driving, and High for High Beam
Commodores also have another added highbeam as the H1 globe, the one nearest to the grill.
Info in your service log manuals, service manuals and tech cds.
