The bottom lens assembly has the daytime running lights (DRL), turn and side marker/parking lamp. On my 2006 "cat eye" I am pretty sure the DRL bulbs are on even when I turn on the headlights in the upper assembly.

Here's a picture of all the lights on the front of the 2003 Silverado.

Ok thanks
then i have a follow up question! So the bulb i was wondering about is the daytime running lamp. Is it on all the time when the key switch is on? And if so does it have a seperate fuse location? Thanks

Based on what it says about the description and operation, I was wrong. It only runs when the switch is set to AUTO, the ambient light sensor on the dash sees that it is daylight, and you are not in park, and the key is in the RUN position.
