Light bulb sizes

[carsonj493]

My Brother has a 2016 Colorado, and I would like to get him some LED lights for Christmas to replace his Reverse/backup lights, cargo lights, and license plate lights. I looked around to try and find the light bulb sizes but can't find much info on bulb sizes, I believe the reverse lights are 921, but I am not entirely sure.

 

I would appreciate it if someone could let me know what size bulbs I need. I would hate to order the wrong ones. Thanks in advance.
