Hello, I am John, a Ford dealer technician.
I hope I can help solve your problem quickly and accurately.
You should be able to replace these bulbs without removing the headlight assemblies. Also, just in case this car has less than 36,000 miles this is a covered warranty part. If you wish you can take this to a dealer and they will replace it for free. If not I am posting the Ford instructions to further assist you.

important to me so please leave accurate feedback for others to see my job performance.
You will have to get some pliers on it to turn it. These can be pretty tight. If you still can't get it you may need to remove the headlight assembly so you have better access to turning it. I'm posting the instructions on how to remove the headlight to further assist you.
