No...i know ur problem now, and this is what i did.
I had a partner push not too hard on the tailights while i screwed the tailights in.
Then i put the bulbs in, and had the same problem with what your having, so what i did was i got an x acto knife and sliced a little bit of the plastic, so that way i could fit the bulb in.
You dont have to do this, but you have a chance of either ripping the plastic or just getting a bunch of cuts on ur hand lol from trying so much, plus if you ever wanna remove it it would be easier to just cut the plastic a little anyway.
I also found that that bulb sticks out farther then the other ones and interferes with the plastic clip on. You could put the plastic clip ons back to make it look neater, but they wont be fitting right. I just took them off.
