Bulb part #'s?

[UnderDawg]

 

Hello everyone. I just got this truck and I was searching through the owner's manual and I was wondering about bulb part numbers. I'm looking to replace the DRL's with amber lights and might change the High/Low beams to the SilverStar bulbs. Where can I find the bulb #'s in the manual? Thanks in advance. Forgot to add it's a 2001 GMC Sierra Z71.

go to the automotive section plug in the yr and model and it will give you every # for every bulb in your truck
