412 warning lights

The warning lights on my 1988 412 are not the same as in the user manuals. On the left side speedometer cluster I have 4 lights - on the far left is a red lamp that says "Ex. 1-6". The next is a green lamp that indicates turns left and right. The next is the blue lamp for high beems. The far right is another red lamp with "Ex. 7-12."

My question is: What are the two red lamps - "Ex. 1-6" and "Ex. 7-12"? I can find no reference to these anywhere.

By the way - the Ex-1-6 came on intermittently, prompting this inquiry.
