Hello and good evening. Below you will find the procedure to replace the headlight bulb. It requires the removal of the front bumper fascia to remove the headlight assemblies. I've got one of these cars too, and yes the bumper needs to come off.

How can I install headlight bulbs in 2005 Cadillac CTS without taking fender off?
Expert:  Ivan replied 3 years ago.
I assure you that this is the way. That info is directly out of the service manual. You could try just removing that inner wheel well panel that is shown in that picture, but I don't believe you will have the room to get the bulb out. Try it and see.
