Got a question, 94 Celica GT Options

[fireman8]

I'm new to this Celica Forum. I bought a 94 Celica GT for my daughter to drive when she gets her license in July. In the meantime I've been driving it because of the gas mileage and the thing has grown on me. I can see where you guys and gals get your enthusiasm for Celicas. I paid $1700 for it and it's in pretty good shape but needs some minor work. Engine and drivetrain have 165,000 on it but it runs smooth, everything else is mostly cosmetic. I have found sun visors on this forum and am looking for various other small parts. I'm amazed at how friendly and cooperative the posters are with questions and help! Here's my question, there is a toggle switch right above the air vent to the left of the steering wheel. It has a cicle and a line on it. Can't tell what it does when I turn it on and off. I don't have fog lights. Any ideas? One other thing, how do I insert a picture on these posts? When I click on insert image it says you must enter a URL. Not sure what that means or how to do it.
