Need help with my 1986 caprice

[d1g1t14l_sku11s]

i have a 1986 caprice classic brougham.4D,305 V8, and the light,which i am unfamiliar with,spotted to the right of the battery light,keeps coming on when the car is driven. i have recently replaced the battery and had the old and new one tested. the new one works and every time this light on the dash comes on it will eventually bring the battery light on and cause it to ding and i am not sure if it is a glitch or something that is a serious problem. Anyone that can help,I would appreciate it.Thank You

Bad EMC or connection to the ECM? Faulty wiring to the idiot lights? Not too sure. If possible get your ECM checked out.
