Original-equipment vehicle light bulbs tend to be of significantly higher quality than the aftermarket-grade (i.e. "nobody cares grade") bulbs that can be bought at parts stores. Even where any particular brand of whatever bulb can be bought either at a parts store or through an automaker's parts system, the automakers generally get, and therefore sell, higher-quality bulbs. It's principally because the consequences of a bulb issue are greater for bulbs bought, handled, and sold by automakers versus for bulbs bought by a consumer. Why? Because automaker-supplied bulbs are used for repairs under warranty, for improvements described in service bulletins, and for recall repairs, so any bulb problem winds up costing the automaker money and reputational stock, plus the consumer's even more upset than if they'd had the same problem from a bulb they just picked up at the parts store. So, here is a list of automaker part numbers for OE-quality bulbs. It will keep growing as more information is added and new knowledge gained, but no guarantee of accuracy can be provided because nothing prevents an automaker from changing suppliers or specifications on any part at any time. Special thanks to RobertM for getting this list started.
