Why is my emergency light on my 2004 ford explorer on?

You are going to have to explain to us what an "emergency light" is.

If by "emergency" light you mean "check engine light" you probably have something wrong and need to go to a reputable parts store or mechanic to run the diagnostics on it. But as for "Emergency" light, i have no clue. It could be some new thing ford started putting in cars and not telling anyone about and youre the first one that has had it go off. You might have ebola and your suv is trying to help you…
