I actually haven't changed the bulbs yet. I didn't have the bulbs in hand when I was changing them in my wifes car. I currently have the bulbs sitting on my table, so I am not 100% sure I have the right size, I hope I do. I removed the cargo lights at first just to see what type bulb they were.OK - I tried that and it didn't work. I was able to reach in from the top of the surround and simply puch the light out. The LEDs I had on hand didn't fit - too big. These were the one's I used on the dome light. What size bulbs did you use? I cant find a listing that shows the bulb type.
