I did try bending them inward a bit with a small flathead screwdriver but that also didn't work. I also didn't feel comfortable bending them so I didn't go very far. Bulbs are way cheaper than that part I'm sure..

So I've already shipped the bulbs back to the company and will get some that are compatible.
