Stock Headlight Bulb is?
#2
Its not a bulb, per say, it s sealed lamp unit. The GM part number is 16510872 and retails for $67.54 or you can go to any parts store and get a H4351 lamp. You can go to an Autozone and get a SYLVANIA brand lamp(part number H4351XV) for $25.99, this is for the low beam...which I'm assuming is what went out. The H4351XV is extra bright and won't match the other side; therefore, you may want to replace the other side too but if not the ask for a standard version
