Can someone help me identify this red light on the left panel? It's from a 1975 GT Junior 1300 (2nd series)
Yes.. indeed . My '69 didn't have it. I think a '75 is a smooth nosed S3.. your manual is dead on Brian.As far as I know, Series 2 GT Juniors did not have a light or switch in that location. Your car is more than likely a Series 3 and the light is a brake fluid warning switch.
