BMW: Instrament Light on, e30, red light

Question
Just purchased an 1990 325i, mint!!! but when I picked up the car driving home a noticed a red light was on looks like this (((0))), but the senser check passed and there is not check engine light, drives great. what is this light for (((0))) should it be on, or should something be fixed

Answer
Robert,
 I'm actually not sure what that light is.  I've never owned an E30 that had this light, or seen it come on.  It might be for the alarm or some other option that was rare.

 Check on www.e30tech.com, or www.bmwe30.net.  

 Good luck,
 Josh
