I want to swap out my instrument cluster lights for LED's but I cant seem to figure out the bulb size I need to do so. I have an 04 silverado 1500.

 

I believe it is a 196, they have vids all over youtube. Also, I literally just bought red led bulbs yesterday to do my cluster and summit racing had some nice prices on them. You can get the bulbs there and the bulb sockets( think that is what they are called) for the bulbs to go into the back of the cluster are available at auto zone or ebay.
