Just don't force it, you don't want to damage those pins.
Thanks. I tried putting the bulb alone (without the base) in just to see if I could get it to slide into the pins and that didn't work. I really think the pings are too "wide" for the sockets or maybe I just had a bad batch. I got mine from ebay though (909 something). Did you get yours off ebay too? They all look the same to me though...
