Ive gotta 2005 Silverado RegCab.. and cant seem to activate on of my head lights ( the one in the red circle).. What is it for... where's the switch.. Its got a bulb in it I just cant figure out what its doing there

 

daytime running lights maybe?

 

Isnt that the outside yellow light/Blinker? Which IS on all the time

 

Your daytime running lamps are the inside light on the bottom. They come on when the truck is in gear during the day. If you wanna test em, then you can put on the parking break, put your truck in second gear, and look at them. If it's in daylight (your headlamps are off) then they should be on

 

Which most of them burn out allll the time

 

Ahhh I never put the truck in gear and GOT OUT to check.... Ill check that out

 

i usually just pull up close behind someone at a redlight and make sure all my lights work!!

 

yes daytime running light. Necessary in Canada

 

Thanks everyone...

 

I have seen some guys run the amber lights in there for a different look. It's the same bulb number just with the NA behind it. 4114 or 3157? I think those both work. I'm sure someone will correct me if my numbers are off.
