i just got a 1990 rx7 gxl and i need help please!!!

this is no major thing but i have a switch in my center column that i do not know what it does it has a half cirlce and bunch of wavy lines please help, thank you

I believe that's the flood light switch. They only work when the headlights are on.

yea, my 91 has that, took me 2 weeks to figure it out, its for the fog lights or flood lights or whichever they are called, wavy line part down should be off if I remember correctly and its the same as mine
