I have a 1981 Corvette built in St. Louis for expot to Canada. Can anyone tell me if Canadian cars had diffrent head light bulbs I have talked to the last 2 owners I am the 3rd and they never replaced the bulbs. I have a lowbeam that went out the local dealer & my manual say I need Delco replacement bulb 4000 low beam. The car seems to have come from the factory with Power Beam 2c1 as the lowbeams and Halogen s for high beams. The dealer here in St. Louis tells me halogens were not an option in 81. Anyone else out there with a late model Canadian Car??
