Hi, new around here, and been appreciating lots of the tips and info on this site.
Forgive me if this has been covered, but I couldn't find it in a search.
I have an '03 2500HD thathas a factory button for roof lights (I'd like to add an orange beacon for plowing), and the manual makes reference to a wire in the roof, for future use.
Anyone know where the wire is located?
I'm thinking I may need to remove the headliner, but hoping it's a bit more accesible.
My truck does not have anylightson the roof right now, just the factory button.
Thanks for any input,
Tom

 

Anyone?

 

there is no button factory for roof lites...just a cargo light button..the roof lights come on with the park lights

 

Just wondering, do any 1500s come with roof lights or prewiring? How difficult is it to wire for roof lights?

 

Wrong.
As I stated before, It's for future use (snow plow beacon). The button is located next to the pssgr air bag shut off. I've added a pic from my 2003 Silverado Owner's Manual....looks factory to me.

ok...guess its a yankee thing...not many snowplows in Texas..

When you said roof lights initially,I'm thinking the cab lights like a dually has..i missed the word beacon.

forgive me

 

So you didn't read my initial post, just jumped in with the answer.....must be a southern thing.

Don't most State trucks have those orange beacon lights?
I don't think it's specifically for snowplowing.

I guess I'll head to the dealer and talk to a GM tech, I'm sure he'll know.

 

it needs rpo 5G4, TRW, or VYU,which you obviously have,....
its brown and black wiresblunt.The blunt cut wires run up the left B-pillar into the headliner

 

Thank You Argon.

I have that button also, but is it really for the amber beacon lights or amber clearance/roof lights? I would like to put on the clearance/roof lights but would like to know exactly if this is what the button is for before i buy them.
