: To change the bulbs all you have to do is put a flat blade screw driver on the right side of the bulb housing and gently push to the left. This will release the catch holding it in and it will drop out and down on the end of its wiring connector. 1/4 turn the bulb and remove. Replace the bulb and just put the housing back into the opening left side first, then just push up on the right side till you hear a click. Takes about 1 min per light. Works for all Deville types 00-08

There are two (2) bulbs. Gently remove the plastic lens, sometimes there is a slot for a very small flat tipped tool (screw driver) to remove lens. You will then see a white plastic clip, gently push to the side and pull down this will remove the bulb casing. Twist the bulbs out. If you purchase auto part bulbs, you must bend the two electrical wires to the sides of the bulbs or they will not work. Cadillac soldered the bulbs into the plastic holders, but it is to the side not the way the bulbs come. Otherwise you will need to purchase the bulbs from a GM dealer.
you need to remove the inside panel to get to these bulbs
i got a 1993 Cadillac Coupe Deville and my turn signals was doing the same thing and I got new bulbs and still didn't work. I had to get a fuse to make them work

They are located inside the trunk lid, underneath the felt lining. You need to unsnap and pull back the felt lining to access the bulbs for the license plate light.
From the outside of the car.. Just un-screw the two screws and change the bulb.
