Re: looking to change headlights on GM 2000
A fellow Canadian - welcome to the forum.
Forgive me if I'm wrong, but I believe by 2000, most cars (if not all?) had halogen bulbs & lamps. Regardless, even if your car did have halogen bulbs, they won't be as bright as they once were. You'll find both lights to be much brighter when replaced with new ones. If Canadian Tire has several options, go with the halogen bulbs. I don't think there is much difference in what brand you choose. One of the major bulb manufacturers has to be making the Canadian Tire bulb. Could be GE, or similar.
You might want to check to see if those "blue" bulbs are available for your car. They are very bright, and quite expensive. Not available for all makes & models, though. Some people like them, some don't.
