I got tired of paying the Dealer like 17 bucks every time one of these blows out. They have offset nubs on the bottom, so they are hard to find. I went to Radio Shack (The Shack), and got a 2 pack of 272-1112 for 1.79. I used a grinder to grind one of the nubs off and like magic, I save 16 bucks per bulb. They are a bit dimmer.
