When I bought my truck it did not have reverse light bulbs in it. I bought 1156 bulbs to install, but they wont fit. They will slide down, but they will not twist to lock in place. If I remove the spring and connector at the bottom the bulb will slide in and twist into place, but it will not twist into place with the spring and connector in place.
I took the entire bracket to the parts store to make sure I had the right bulbs, which I do. And, I tried a new spring and connector, which didn't work either.
What am I doing wrong? Why wont these new bulbs seat into the backup light bracket?
