what do these dashboard lights mean?

What is your question?

where your gauges and your gas light come on there are these other signal lights like check engine etc. well i had one light up and have no clue what it meant. if i could get a way to know what these mean i can better care for my car Is there somewhere other than my owners manual i can look?

How long has your 1991 Geo Metro had this problem?

a few days
