This is a bit of an odd question I guess but it's one i've been thinking about recently when I start up my 180. Wtf are the other little red lights for on the dash that have no icons on the left side of the speedo gauge? Like theres oil pressure, fuel, battery, exhaust temp, door but theres others that have no icon and are never used. Why do they exist? Does anyone actually know? Symmetry? Aftermarket uses? Diagnostic uses?
