Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
The dealer installed 12v d1s globes that don’t handle low and high beam. You need the Philips d1s 85v that handle low and high beam.What do you mean by "make sure they're bi-xenon"?
They use OEM equivalent but not the actual oem brandI'm not really sure what you are referring to. The bulbs are either xenon or not. The high and low beam function is done by a metal flap in the headlight, not the bulb, ie the bulb has no low and high beam capability.
Looks like the dealer didn't use OEM ones.
