I changed mine out. They were a 73 or 74 I think. Little bitty that came from China. Needed 4 of them and I believe I got the CAN bus style bulbs. Had to clip the end off with dikes cause they were too long. Just a little. Easiest way to remove the old bulbs is with needle nose pliers and install the new ones the same way. And be careful when removing and installing these bulbs. If you move them the sides too much you will cross the contacts and instantly blow a fuse and lose both vanity mirrors, your power locks and everything else that's on that fuse. The correct number is on the bulbs though. It's just really small.
