I have an 04 Silverado that I want to convert the instrument panel lights to LED, but when I go to order them online I have no idea what size I need.

 

It’s either a #52 or #56 incandescent bulb - I can’t recall the exact one - the only difference is how bright it is, and there’s not gonna be a very noticeable difference between them when it comes to LED’s.

Choose the replacements carefully - the LED can’t be any taller than the original bulb because of how the cluster is assembled.

A good quality soldering iron is also recommended.
