As I sit here reading the Forum with 4' of snow just about touching my window sill, I can't wait for this winter to end. As do most, I'm sure. I just made an impulse buy on two of these packages from Amazon. I hope my new 2015 Bullet 248 RKS has the 921 bulb, it's sitting at the dealer right now. Why did I click on BUY before I confirmed the part #?? Must have something to do with my current sickness called Cabin Fever. LOL
