In the 2019 Chevy Silverado, the reverse light bulb size is designated as 921 in the owner's manual. The price of replacement bulbs can vary depending on their type and quality, typically falling between $20 and $55. To swap out these bulbs, you'll require a Phillips head screwdriver to remove the tail light lens for access, and the light can be easily pulled out of the socket with minimal effort. Unscrewing it counterclockwise allows you to disconnect the wiring and replace the bulb. Reinstalling the bulb involves repeating the same steps.
