I want to add fog and driving lights to my 97 4wd 4dr blazer.

Right now I have the dash apart cleaning and removing improperly installed stereo/XM stuff and noticed an unused bung behind the headlight switch panel. Is this for fog lights is the vehicle was so equipped...?

I ask because my firebird had such so when I added driving lights to it I used a factory switch panel and just plugged it in for a clean install inside and did my own thing under the hood.

Also....there are repalceable bulbs in my transfer case switch panel. Can I get these anywhere or will I need to visit GM to get these tiny things...?

Thanks much.

 

Heck I've got a 95 4x4 Jimmy and it has an actual fog light switch next to my hatch button but no actual fog lights and there aren't even any wires hooked up to the switch. I've had the dash open. Thing is I've looked, where the fog lights are supposed to go on my truck it has the tow hooks (Basically they go at the frame ends)

 

My 2004 has all the wiring but no actual switch or fogs wired up. It was cheaper to just mass wire the trucks than to say "yes this one, not this one..." so if you're going to buy the lights just run new wires to switches rather than try and use the stock stuff IMO

 

The little light bulbs can be had for about $10 for a box with about 20 of them. NAPA can sell them. They wont be able to look up a part number for it, but a knowledgeable guy will just be able to show you the small bulbs they have and you can tell which ones you need.
