1892 light bulb for AC control?

I'm almost positive that I just bought a package (2) of them last week from Advance Auto Parts here in Arvada CO. I needed an 1816 for my thumb wheel radio and they didn't have any of those, but the kid talked me into buying the 1892's then I checked at AutoZone and they had the 1816's so I returned the 1892's. Send me a PM if you can't get them and I'll go back the Advance and get a pack for you. I think I paid $2.99 for 2, Ramcharger's price is better but don't get beat up on the shipping.
